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 [1] 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.
