When I say hard lock / freeze I mean I cannot kill X, I can't do anything, I must hit the reset button on my tower.

AKA kernel panic bsod crash freeze lock frozen

Video freezes on the last frame of gameplay, the audio loops 1 second of sound before the freeze, the network appears to keep working, but I cannot ssh remote in to restart, keyboard unresponsive.

Memory allocation / ownership bug ??

I always use another X session/linux user when playing games. I'm not sure if the lock up happens when using the same user/X session all the time. I do not use switchuser, I quit my previous X session by logging off. Running X on 1 virtual console - F7.

The lockup occurs if I have been developing using my default linux user/X session. Then I decide to take a break and play games, so logoff dev user, login as game user. When I start the game, once game play gets started, the lock up will happen either immediately, or within 10 minutes.

Avoid lock ups by doing the following before playing games. - basically a fglrx reboot -

/sbin/init 2
/sbin/rmmod fglrx
/sbin/modprobe fglrx
/sbin/init 5


Or restart the computer then use the X user/session that I normally use to play games, I have no lockups.

Could the video memory - which is shared system RAM - still be "chowned" or locked by the previous X session?

At first I thought it was other packages, new to fedora 8 but that proved false. Also, I thought there was a fix by turning all 3D options on using amdcccle, but that too is false.

I didn't have these problems in FC7, but ran a different X setup. I would start X on 2 consoles and switch that way.
