Where can I learn about ICH5 SATA RAID driver in Linux kernel 2.6.0? I
have been looking into Documentation/scsi and found nothing containing
the word "ICH5" or named *ich5*. Also the help page in make menuconfig
says nothing. I would like to know the following:
1) features supported
2) interface specification
3) usage guide

Intel "RAID" is software RAID. There isn't any hardware RAID assist...
So ICH5 looks pretty much just like any other PATA host controller.

Oh? My understanding (which I admit is very high-level) is that Intel's
ICH5 southbridge supports SATA; but to get SATA+RAID requires the ICH5R
southbridge. If not, what are the practical differences (if any) between
the ICH5 and ICH5R?
TIA.

None; as I said, Intel's RAID is _software_ RAID. You simply need to
use the "iswraid" Linux driver to access the proprietary vendor RAID
metadata format on your disks.
If you do not wish to be locked into proprietary vendor RAID, then just
use Linux's md RAID, and you may pretend that ICH5 and ICH5R are exactly
the same :)
