You should forget about any kind of RAID drivers and use Linux's md. 
They are both software and md is very well tested.

Installation should not ask for driver disks, but use the ata_piix
driver. If this is not the case, then the PCI IDs from the mainboard
SATA controller are not in the known list; you can find instructions
on the 'net about how to add them and then rebuild the initrd.img file
that will allow you to boot. Then use the installer (-> manual
partitioning) to define a RAID1 array.

If you mix-and-match (RH9 and RHEL9) you'll get troubles - if it works 
at all.

Yes, allow the disks to be seen as just 2 disks.

No. I run about 10 machines with software mirrored (RAID1) disks with 
md; they have various onboard disk controllers, some supposedly RAID 
0/1 capable, but with md it's much simpler.

That's not a guarantee. Do you have any idea if the 2.6 kernel has 
capabilities to recognize the Intel RAID ?
