Yes, Promise Bios have issues doing HW Raid with any OS accept NT. Andre
Hedrick (the main Linux (not just SuSE) IDE guy) that these chipsets are
broken in that they are specifically written for M$ products. I don't
have much of a suggestion as far as RAID with these cards under
Linux..I've only used 3ware cards which work perfectly. You might look
for a newer Bios rev. or try to find some tips at Asus's site about
using these onboard chipsets with Linux.

FYI: Promise has never really released the specs for these chipsets and
they have promised a "binary" driver for Linux, but when it will be
available is a good guess.
