yes, after any resume (Xv output before or not) the Xv output is green garbage.
The only way to clean the garbage seems to restart X.

It seems the patch works only when I forget all modules on boot
(no /lib/modules/2.6.9/ directory)
I can manually insmod sungem and dmasound_pmac, and the sleep still
I tried elimate most of them from a normal boot with modules, leaving only
radeon and apm_emu, and it stills crash.
I'll try to track that.
