I've two almost identical systems (slightly different CPUs) that use
SiI 3114 for SATA and RAID.
One of them was installed a while ago with Fedora Core 5 (kernel
2.6.15-1.2054_FC5smp) and whoever installed it was able to turn on
hardware RAID.
This chip does not support hardware RAID. The capability simply isn't
there in the silicon.

Wow! :-(
So that means that the FC5 system is not actually on RAID? Even though
it seems so? (using /dev/dm-* for filesystem volumes)
# lspci | grep -i sata
03:05.0 RAID bus controller: Silicon Image, Inc. SiI 3114
[SATALink/SATARaid] Serial ATA Controller (rev 02)

So in fact /dev/dm-* are just on one disk each (not RAID1), or what is
going on here?
The's dmraid providing /software/ RAID as noted in
http://linux-ata.org/faq-sata-raid.html#dmraid
