When DRI is not enabled the HEAD branch still uses the old texture upload
approach, while it uses a DMA based one when DRI is enabled. Eventually, both
code paths will use DMA, so we only would need an intermediate fix.

I think that R100 had several hardware flaws (race conditions and undealt
exceptions) that have to be worked around. This is difficult to do without
errata sheets, and I doubt that these even exist for graphics hardware (the
release cycle is too fast paced for decent chip specific documentation). You
typically only get those sheets for products with a long livetime or for
products that are integrated a large number of companies.
