Not necessary, it's just a theory. It would be interesting to rewrite that function to use the 3D engine on r300 and see if it fixes anything.
A simpler test could be to use r200_copy_dma instead of r100_copy_blit for the .copy hook in radeon_asic.c. (On my mobile RV350 that seems to perform better anyway...)
