Don't know if this is valid for < 8.11 but with it I get:
[fglrx:drm_free] *ERROR* [driver] Excess frees: ffffff7d frees, 0 allocs
[fglrx:drm_free] *ERROR* [driver] Excess frees: ffffffff frees, 82 allocs
Two times in a row in my dmesg.
Can this berelated to my box sometimes not returning from GLScreensaver after monitor switched off?
(amaroK still plays so I guess this is X related)
