I have had unfortunate luck of having a semi-new ATI card that, though supported by the linux drivers, will not run The Elder Scrolls IV: Oblivion on cedega with the oldblivion workaround
.

Oblivion causes an X lockup when I try to leave the sewers early on in the game. I was not the first person to experience this bug and we are fairly certain it's a problem with the ATI drivers. The project head, asp (to whom I am very grateful) confirmed that he might be able to make a workaround if I could dump the register values at the time of the X lockup.

I need to use the wine debugger in order to do it...help would be appreciated.
