I'm running a Dell 2650 w/ a PERC RAID controller on a linux box running 
  Mandrake 10.1.

 From dmesg:

scsi0 : percraid
   Vendor: DELL      Model:                   Rev: V1.0

from /proc/pci :

   Bus  4, device   8, function  1:
     RAID bus controller: Dell Computer Corporation PowerEdge Expandable 
RAID Con
troller 3 (rev 1).
       IRQ 30.

       Prefetchable 32 bit memory at 0xf0000000 [0xf7ffffff].

It's using a kernel module called "aacraid", not sure if that's for the 
Perc controller or the other adaptec scsi card used for a TBU.
