Hi,

I don't know if you have any clues to fixed this issue but I've spent my entire week end on it so I'm able to give you some kind of help.

To have a system fully bootable and working, you need to modify the IDE options in the BIOS.
So go into BIOS -> IDE Configuration > Mode : Enlarge (don't know exactly but not Compatible or IDE) and SATA+P-ATA

Then you need to add 2 options in grub to get it booting correctly.
Add irqpoll and noprobe=ata4

Now my system is booting properly and working great, my disks are well recognized

FYI, I sent an email in the IDE/ATA team kernel developement but no answer (it seems that I'm not the only one). I crossposted them because this bug should have been fixed into the 2.6.23-rc2
I tried with a 2.6.25 and it wasn't working no longer too so I think this bug is still present
