Mauro, have you tried to format and partition the disks from a GParted
LiveCD before running the installation? This way you can omit this step
from Debian installer, though I think this is something worth reporting
in BTS, either if you can bypass it with Gaprted or not.
On a completely side note, have you considered in using a different RAID
level (e.g., RAID 1)? I think it would be a better option for holding the
operating system.

This is quite weird. How have you setup the hard disk controller at the
BIOS? What are the available options for a non-RAID layout (JBOD)?

Hum... this is interesting. It points to some sort of problem with
Squeeze's installer :-?

If the kernel supports the RAID controller there should be no need to
load additional drivers. The fact that only a hard disk is detected when
you have configured a RAID 5 setup means the card is properly recognized.

I would first try to use Gparted and see what happens.
