AIW Radeon and VIA chipsets

I've been shopping around for a new system based around a 1.2 Athlon with a VIA or AMD 750 chipset, I haven't decided if the DDR is worth the extra money (no motherboard preference yet). I'm leaning towards the Millennia MAX XP at micron. Problem is nobody seems to be offering the AIW Radeon when configuring the system. I emailed the sales department at ABS Computers and this was their response, does anybody know or have experienced this incompatibility?

"Up to now, the All In Wonder Radeon did not function properly with the VIA chipset... new drivers by VIA could solve the problems but we have not yet completed our testing."

Thanks in advance...
