2.4 would only support the sata as an emulated generic ide device
(/dev/hda). 2.6 would try to use it as native sata using libata and
would have the drive appear as /dev/sda. device 3,2 is hda2, while sda2
would be 8,2. Try changing it to 'root=/dev/sda2' instead of hda2.

Not their problem. Nothing they can do about it.

Unfortunately from what I have seen lately, there has been a lot of
problems getting SATA natively to work on the SB600, and you may have to
go to 2.6.20 or 2.6.21 before it actually works reliably at all. Either
way you have to use /dev/sda rather than /dev/hda in your boot menu and
your /etc/fstab file. Starting out with a 2.4 kernel on a modern system
is just a cause of lots of pain due to the device name changes.
