Are you sure the adaptec driver is not in the kernel. I have adaptec to be very good, in terms of opening up their drives. I have not come across one that wasn't already in the kernel.
I have used SCSI and SATA Controllers and RAID variants of each without getting any drivers from adaptec.

Unfortunately in this type of situation, I'm not sure you'd get much
help by using an older kernel - the driver may well not behave itself
well enough to still work under Xen... At least, I think that is still a
problem in Xenified Linux as it is under HVM - drivers in Xenified Linux
are modified to "understand" Xen, and that's not going to work with
binary drivers. However, I may be wrong. Someone with better
understanding of this may be able to correct me (or say I'm right).
