When using the 2.4.22-xfs kernel (Knoppix -> Debian installation), our
SATA root drive shows up as /dev/hdg, but under 2.6, it's now a SCSI
device, /dev/sda. It took us a while to figure out what was wrong until
we finally got a serial line and were able to read the boot message
outputs.
This is the error message we got originally _before_ we appended
"root=/dev/sda3" to our command-line:
VFS: Cannot open root device "2203" or unknown-block(34,3)
Please append a correct "root=" boot option
I have a feeling this will take a lot of SATA users by surprise, so
hopefully it'll be documented from now on.

you can use SATA drives as scsi drives on 2.4.x kernels too (I use it
with 2.4.21-ac4), actually at least in my case it's better because when
I try to use it as IDE drive the system freezes (during probing IDE,
right after it prints out the info about disks).
