This all looks OK AFAICT. However, I don't know much about h/w raid or
even whether the card in question is a 'grown up' RAID card or a 'quasi
raid' card. There are cheap 'RAID' controllers that don't provide full
RAID capability, under Linux at any rate - I'm no techie and this is
what I've picked up from the list and from my own experience with a
Promise card.
I would disable H/W raid and use software RAID in Debian by installing
the mdadm package. I've got it working on a number of servers (SATA and
IDE), faultlessly. The only problem I've had is that some kernels don't
load the requisite Sata modules before the boot process tries to check
the disks, hence putting them in /etc/modules.
I put some brief notes up but the links therein are (or were) very
useful.

Sorry, I can't be more help.
