Oh, I get it now.  Adaptec's Hostraid line isn't really hardware raid, it 
still needs host OS support.

Well, it did look like hardware RAID at first (up until the point when I 
actually tried to boot Fedora).  After enabling RAID, subsequent POST 
enumerated a single device, on the lowest SCSI ID of the two drives.

I can't find SCSI stuff on 3ware.com.  They look to be in the business of 
ATA RAID only.

Looks like my only option appears to be LSI Megaraid 320-1.

/lib/modules/2.4.22-1.2140.nptlsmp/kernel/drivers/scsi/megaraid.o

That should work..
