Is hardware RAID supported?

I'm getting the impression that the nForce 250GB chip set is actually
not fully supported. My Soltek SL-K8AN2E-GR mother board has this chip
set. I currently have hardware RAID+0 setup in the CMOS which is working
with Windows XP Pro. The last few days I have been reading around the
net and I finally came across information that basically states that
hardware RAID in GNU/Linux is not supported.

Is this correct?

If I want to keep the hardware RAID setup, am I restricted to the only
option of adding a third HDD to this system if I want a dual boot
GNU/Linux & Windows system?
