Are you sure it's this way around?

Needless to say, that's a BIG difference in available texture memory, 
and unless you turn down texture detail to the lowest setting (and I'm 
not sure this is enough) not all textures will fit into local video mem.

btw, you have

So, this is a r100 class chip (with presumably 32MB 64bit DDR ram?), not 
r200 (rv200 is not r200), though this means the driver will at least be 
able to use AGP GART for textures (r200 driver won't, causing texture 
thrashing, manifesting as heavy stuttering).
