Newer Adaptec RAID controllers usually use either aacraid or i2o_block 
driver (the DPT I2O based controllers).  If your's is using aacraid, 
you'll see the volumes as /dev/sd*.  If it's using i2o_block, than 
you'll see the volumes under /dev/i2o/hd*.  Try booting off 
installation CD into rescue mode and see what modules get loaded into 
the kernel.

Word of warning, i2o_block device driver seems to numerate drives in 
different order than BIOS, and depending how it is loaded it might 
numerate them differently (for example, I always get different order in 
rescue mode than when system is booted normally).  In some cases, 
you'll need to instruct your boot loader what the BIOS thinks is the 
first drive (for example, I had trouble with LILO and this controller 
in the past because of that).
