'Cannot open root device "801"' after kernel update to 2.6.12...?

I updated my kernel to 2.5.12 and ever since I get the following kernel panic in my dmesg. Anyone know what's up?

SATA goes from sda -> hda

It seems that previously my SATA devices were /dev/sda and under the newer > 2.6.12 they become /dev/hda. How do I fix lilo to work with the new device names? Did their major device numbers change too?

More things I tried...

It seems that SATA drives can load thru the SCSI libata or through the IDE drives. One tip I ran across was disabling probing of hda with hda=noprobe. The site said that this would force the SCSI SATA support to kick in, but it doesn't seem to work that way for me. hda is not probed, there is no sata, and I get the same "Can not open 801" thing.
