i also had the same problem, but we might have a different hardware. I use Promise "SMARAID", i think this is also the same as Promise Fast Track LP (it uses PDC20265R chip).
Anyway, i just want to share what i did,
1. Boot Slack 9 installer using the ataraid.i kernel.
2. partition the harddrive by using the command fdisk /dev/ataraid/dp0
3. then run setup normally.
I had the system running for 3 days straight with no problems so far, unfortunately, our EDA tool uses Red hat so i am now attempting to make it work with RH9. and so far no luck.
Hope this helps.

Update, I can start a dedicated kernel: ataraid.i install of the bare.i which is supposed to support my promise fastrak card but what after? Still can't see my partitions.
