sata_sil loads but won't recognize striped raid

Description of problem:
Fedora Core 2 runs fine, and recognizes SATA drives, provided I don't
use raid. But with striped raid neither fc2 nor fc3test3 installs
properly. Anaconda loads the sata_sil module, and recognizes that I
have sda and sdb drives. But it says that they aren't formatted
properly. It offers to wipe them clean, which I refuse. Then it is
still willing to install fc3 on an IDE drive. OK, but I want to put
it on the SATA raid drives.
Here are the gory details. I have Gigabit GA-7N400 Pro2 motherboard
with nForce2 chipset and SATA raid with chipset Sil3112 (also on the
motherboard). The SATA raid is set in BIOS to be a striped set,
connected to two identical Maxtor 6Y160MO SATA hard drives, 160GB
each. The CPU is Athlon XP 3000+. The striped set is working
properly, because a Windows 2000 install program can see it once the
proper Sil drivers are loaded.
I suspect the problem is with sata_sil module. Apparently it is not
correctly recognizing that I have a striped raid set.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Set up a striped sata raid in BIOS
2. Start anaconda in normal mode
3. Get to point where it is ready to partition
Actual Results: Anaconda doesn't recognize that I have striped SATA raid.
Expected Results: Offer to partition sda (after recognizing that it
is striped raid).
The various IDE RAID adapters out there don't actually provide a real
"hardware" RAID and are instead completely software. The kernel does
not at present provide support for this functionality.
