I believe that the SiI 3112 is surpassingly craptastic ... However, it
is the only option that allows me to RAID both my windows partition
and my Fedora partition. What I find surpising is that Windows has
remained oblivious to the whole thing and has booted consistently.

I did try to fall back to setting up a software RAID but was thwarted
by anaconda telling me something like "this configuration is
unavailable on this platform" as soon as I hit the RAID button in the
partitioning step. Maybe this is just a bug in the latest test
installer.
