32 matrices is just a feeeeew two many for ATI cards, but of course

their drivers can't do anything useful like report an error; they just 
silently screw up.  Limiting it to 31 makes it work, but there's still a 
strange slowdown issue (and it's not that the shaders are being run in 
software, but it's worth checking for that anyway).
