I just got a system here using the exact same motherboard and I've
been working on trying to make it detect the SCSI-devices. I've gotten
as far as noting that there should be AIC-7890 support in the kernel
(Atleast in my 2.1.107). However, Adaptec uses another PCI vendor ID
for this chipset on the ASUS motherboard and has no knowledge
whatsoever of the AIC-7890.

After having inserted this information (included below) into the
PCI-drivers, I've gotten so far as to make the kernel acctually say
what it is in /proc/pci, but the scsi still doesn't detect any hosts.
Any suggestions would be warmly welcome.

The ASUS P2B-DS motherboard (and probably others aswell) uses an
AIC-7890 SCSI storage controller with the following data:

PCI_VENDOR_ID 0x9005 (Adaptec)
PCI_DEVICE_ID 0x001f (AIC-7890)
