If rect500 and copywinwin500 both drop I would say your clocks are
lower now than they were before. If only rect500 drops and not
copywinwin500, I would say you lost block mode fills (SGRAM special
features aren't being used anymore - It's treating the card like
a dumb SDRAM card). It could be that you have framebuffer device
support in your kernel and it messed with the chip.
