There's now hpsa driver which shows at least some cciss controllers as normal scsi devices - cciss in ML150 G6 is 103c:323a (rev 01)

This might be confusing for users, to know when it's cciss bus and when scsi,
We'll need to talk to kernel storage to see what's the plan with separate cciss driver, both hpsa and cciss are present in 6.1:

Comment 1 Mike Burns 2011-10-25 18:06:43 UTC 
hpsa devices show up as /dev/sdX, cciss devices are /dev/cciss/c0d0
