It is usable as a SATA host (controller). The RAID function is not usable
yet, and since it is crap (software-assisted winraid), you are better off
using linux native software RAID anyway.

In _any_ case, you need the kernel to have the drivers for the chipsets
compiled in (or appropriate modules loaded). The SATA disks will show up as
scsi disks, I believe.
Not many chipsets are supported, but hopefuly the Promise ones are... you
_will_ need a very recent kernel (2.4.23, 2.4.24-pre or 2.6.0) and maybe the
libata patch. Search google for more details...
