Not sure about this one, anyone with a SATA controller that could test.
I think I also read something about some bios settings that could

Well, Megaraid2 drivers are not availible for 2.6.8. People who install
servers using megaraid2 (scsi megaraid), would have to use linux24 at
the boot prompt when they are installing their server.

tg3 is mostly working out of the box with 2.6.8, I haven't seen it lock

6) if you install 2.4-kernel, then upgrade to 2.6, you wont get working
/dev/pts, which breaks a lot of things, including Konsole/Xterm and
ssh. see http://bugs.skolelinux.no/show_bug.cgi?id=961
blockers for using 2.6-kernel:
1 and 4 is gone
2: I dont have any SATA machines were I can test this
in favour of using 2.4-kernel:
3: Missing megaraid2 drivers on 2.6-kernel
in favour if using 2.6-kernel:
5: missing sata drivers in 2.4
6: ptys are missing if upgraded later (#961)
