lists.x.org != lists.freedesktop.org :)

Try without these two options.

For the former, values larger than 32 (which is also the default now)
aren't handled correctly automatically for PCIe cards.

For the latter, the Mesa r300 driver doesn't properly handle GART
texturing, so it needs to have texture space in video RAM.
