Thanks to *NeddySeagoon *from Gentoo forums, I've been able to resolve
my problem. It turned out not to be RAID related at all: I made and
mistake in configuring support for my IDE controller!

Howdy, I'm trying a new install (since I hosed my last one) and I
figured I'd give the RAID+LVM thing a go. I followed the guide at
http://www.gentoo.org/doc/en/gentoo-x86+raid+lvm2-quickinstall.xml and
everything seemed to have worked ok, but when I boot I get 3 no-fun
(TM) lines:
VFS: Cannot open root device "md3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
Now, my relevant grub lines read:
root (hd0,0)
kernel /boot/kernel root=/dev/md3
My partition layout is just like the one show in the guide:
/boot -> RAID 1 of hda1 and hdc1
swap -> hda2 and hdc2
/-> RAID 1 of hda3 and hdc3
LVM -> RAID 0 of hda4 and hdc5 (I used an extended partition on hdc
because it it much larger than hda and I wanted to create an hdc6 for
the additional space)
I am able to boot from the livecd and mount the arrays just fine, so I
believe it might be a kernel problem. But I did enable all of the
necessary kernel options listed in the guide and they are built into
the kernel (as is ext2/3 which are the only file systems in use). Any
clues?
