I've been looking into this issue recently, and have found out a few interesting
things.  The pre-rendering workaround patch does not solve the problems that I'm
seeing on my R100s and RV200s.  However, I found that I could work around the
problem in one of two ways: either change the PP_TEX_SIZE_0 from "(height-1)<<16
| (width-1)" to "height<<16 | width", or force the code to never use
non-power-of-2 textures and fix the dst_pitch to always be a power of 2 (instead
of just a multiple of 32).  Neither of these changes are required for R200 and
newer chips.

I'll attach a patch next that works around the problems for me.
