I came to the conclusion that the xserver DRI2 invalidate patches that
have been discussed aren't really fixing the problem. I suppose they may
make the problem slightly less likely to happen, but at least for me that
likelyhood is still very high. The whole mess looks like a simple driver
bug to me.
These patches make unredirecting fullscreen windows w/ compiz + page
flipping work a lot better for me. I've still seen an occasional complain
from the kernel  and one time the kernel went into some infinite page
fault loop, printing stuff endlessly to the console, but other than those
things seem much more solid now.
