Most of the inexpensive SATA raid cards are really doing software raid
in the bios. Have you tried one of these:

I've only used the older IDE versions but they are real hardware RAID
and appear as scsi devices to Linux. The 8500 series has been stable
for a long time with Linux drivers included in the kernel and I think
the 9xxx versions are solid now.
