As I said, current processors have no optimizations for AGP/PCI read cycles when running in write-combining mode, each one is a completely separate synchronous transaction. There is a small speedup available on 16-bit frame buffers by reading 32-bits at a time, but that will become less important as more people migrate to 24-bit displays. Some people are successfully implementing significant Render acceleration with hardware; that's clearly the right direction to go.
