Hey, all. I just wrote a patch based on the suggestion from Kevin
Brosius. This is an attempt to help account for differences in the FIFO
registers with the virge/GX2 and the other virge chipsets. So far, this
patch has worked quite well. No lock ups from the moire2 screensaver. I'm
using the following options now:
Option "XaaNoCPUToScreenColorExpandFill"
Option "pci_burst"
Option "pci_retry"
Option "fifo_aggressive"
Later for now.
