PCI ID is unknown in /proc/pci for Neomagic chipset.
SVGA server can't detect exactly what to do with it, either. Unsure if
this is due to the kernel not knowing the chip ID, but it appeared
that may be the case.
My 600X *is* available to RH staff to poke at if they'd like. Just
Add 'Chipset "NM2200"' to your 'Device' section; this makes it
think it's one of the older chipsets, which seems to work OK.
Yes, we should probably fix Xconfigurator at some point.
Fixed in Pinstripe
