Don't know if anyone actually cares but 8.42.3 (with FireGL hack) is running fine on my Thinkpad T60p (FireGL V5250).
Only thing that's annoying is the missing suspend/resume but I can live with that (for now).
Even ET:QW runs fine and stable.
This thread is now being closed. If you run into issues with fglrx 8.42/8.43, be sure to upgrade to the latest ATI/AMD Linux driver and create a new thread or use a newer "driver released" thread.
Can we get an unsticky and a close on this?
