Debian GNU/Linux on Dell Poweredge 2950 with PERC 5/i RAID

I had the same problem, but in my case on a 1950.
The driver in question is megaraid_sas, at least with my 1950.
I poste a message a while ago saying exactly what I had done to fix it.
See it below.
It should work with the 2950 as well.
I tried to install debian etch on a 1950 yesterday, the installation
worked pretty well, but it froze during boot up.
As is guessed, the initrd that comes with etch doesn have megaraid_sas
I figured out a small "hack" if you still want to use initrd(I haven't
used yaird and I didn't have the option to do so during my install)
When the installation finishes, do not restart the machine.
Press CTRL+F2 and go the shell
"MAKE SURE YOU chroot INTO THE RIGHT ROOT PARTITION BEFORE RUNNING THESE
$chroot to the root /target/"something" partition.
Edit "/etc/initramfs-tools/modules" and add "megaraid_sas" to the end of
Copy /boot/initrd.img-2.6.XXXX to /boot/initrd.img-2.XXXX.old
Run "update-initramfs -u" to update the current initrd to include the
Reboot.... and that's it. A working debian etch on Dell 1950.
I'm not sure if this has already been reported to Debian, I'll check it
Hope this helps.

It sounds like the real problem is that the megaraid_mbox driver is not
added to the initrd. It should include all driver modules need for boot
are not built into the kernel. you can force modules into it by adding
one per line to either the /etc/mkinitrd/modules or
files and then running "dpkg-reconfigure
Fill in your correct kernel package information for the reconfigure
