My problem only became apparent with a newly built motherboard which does have SATA stuff in its BIOS. I don't understand much about this and am reusing my old disks so I turned it off.

I actually had already compiled a 2.6.13 kernel from kernel.org, as I mention, and also dpkg-ed one from the experimental release. Both work fine, but the non-detection problem is identical with both of them and 2.6.12, because the source of the error is somewhere else. I backtracked the problem to the SATA disk my comp has. The 2.6 kernels recognize it as SCSI at boot, so they load the ata_piix module, which subsequently blocks loading of ide-core, ide-generic etc. Actually, these modules are loaded at some point, but they complain that ide0 and ide1 are already taken (ata_piix seems to have "hijacked" them). I intend to upload my epic odyssey to my Linux "trick page", and I might post a link, if I don't find it too lame :^) My solution, in short, has been to insert these lines in /etc/mkinitrd/modules: ide-core cdrom ide-cd ide-disk ide-generic (the order is important, because of inter-dependencies that are not held properly at the boot time where these options kick in, since modprobe is not available to the kernel or whatever). Then I made a new initrd image for my kernel, reading the file above: mkinitrd -o /boot/initrd.img-2.6.12-1-686-smp.custom 2.6.12-1-686-smp and the final touch would be to insert the corresponding line in /boot/grub/menu.lst.

[snip]
I have a similar problem here, and sysfs won't help. My
/proc/sys/dev/cdrom/info file is empty (contains the "drive name:"...
entries, but w/o a value). Also my /sys/bus/ide/devices/ dir is empty.
I am running Debian Etch with kernel 2.6.12-1-686-smp (on a P4 with
HT), udev 0.070-2.
If I boot under 2.4.27-2-686-smp (w/o udev, of course), the /dev/hdc
device is created, and I can mount a CD just fine. With 2.6.12, not
even dmesg acknowlegdes the presence of the CD drive, no /dev entry is
created, and no info appears in /sys (I mean, regarding the CD drive).
Maybe, just maybe, it has something to do with module ide-detect?
Kernel 2.4 has it, but not 2.6. Somewhere I read to add "ide-generic"
to /etc/modules, in place of "ide-detect" (which would only make the
system complain everytime I booted into 2.6, anyway), and it didn't
help.
Another idea is: does it have anything to do with the fact that 2.4
sees my SATA drive as IDE, and 2.6 sees it as SCSI? Maybe 2.6 doesn't
find IDE drives, and doesn't load some modules which are later needed
for the CD? I seem to be seeing them loaded, however:
#>lsmod | grep ide
ide_cd 43748 0
cdrom 41088 1 ide_cd
ide_disk 19104 0
ide_generic 1376 0 [permanent]
ide_core 132352 4 ide_cd,ide_disk,ide_generic,usb_storage
I have to add that I disabled hotplug on boot (after doing a "lsmod |
awk '{print $1}' >> /etc/modules"), because it made the computer take
forever (over 15m!!) to boot. Now, w/o hotplug, it is much faster, but
still very slow. And before anyone jumps on me, the problem was there
when I was running hotplug...
Can someone help?

The kernels I have are both linux-image, i.e. the standard Linux images as obtained from the Debian mirror. I've tried compiling vanilla kernels but for some reason they fail to do so, both on my desktop and my laptop. This a new development; they always used to compile in the past without problems.

Do you mean /dev/cdrom? That used to exist, but I believe it's been deleted: it used to be a symlink to something like /dev/hdc (or whatever your CD-ROM drive device was), but lots of people have multiple CD/DVD drives; how is Linux supposed to know which one to symlink to? The proper approach now, I believe, is to use sysfs. See below for the info on my system. It says that my CD drive is /dev/hdc, which I can then -- if I want -- make a symlink to. I don't know how to make that symlink permanent, such that /dev/cdrom is there when I reboot.
