It shouldn't. IA64 is itanium.

Disable raid in the bios, and setup software raid in linux. It is a
better solution.
Hardware raid isn't cheap since it involves a dedicated cpu to do all
the work for the raid (although for raid1 that isn't much at all).
Faking it with the bios and the drivers isn't any better than doing it
straight in software in linux, and at least then you can see what is
happening and control it, and it is portable to other systems unlike the
fakeraid setup which usually won't work with any other controller.
The installer might even see the drives when the controller is back in
it's native sata mode. Well at least the etch ones might, the sarge one
might not.
Make sure to boot the 2.6 installer kernel on sarge, not 2.4. No chance
of 2.4 working on that new a system.
