Under 2.6.37:
$sudo mount

proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)

rootfs on / type rootfs (rw)
/dev/sda2 on /home type ext3 (rw)
So the only difference between the 2 is the "/dev/sda2 on /home type ext3 (rw)"
line, which appears only under 2.6.37.
The rootfs entries are interesting. I believe they are used by initrd,
but should be overwritten by proper /dev entries later in the boot process.
What's the content of /proc/partitions for both kernels?
Under 2.6.33.3:
$ cat /proc/partitions
major minor #blocks name
3 0 156290904 hda
3 1 9767488 hda1
3 2 58597087 hda2
3 3 979965 hda3
3 4 86943780 hda4
Under 2.6.37:
$ cat /proc/partitions
major minor #blocks name
8 0 156290904 sda
8 1 9767488 sda1
8 2 58597087 sda2
8 3 979965 sda3
8 4 86943780 sda4
So the kernels see the partitions, but .33.3 doesn't have the device
files. Then I think there's some problem with udev. Check the output of
"udevinfo --export-db" with both kernels to know if udev sees your disk.
Also see if you can find your partitions in /dev/disk/.
