[Xorg-driver-geode] Get cim_gp_ptr and the like in another program

[Dirk De Becker]

Hi Jordan,

Sorry to bother you again, but I'm totally new to this kind of stuff. 
Could you tell me exactly how to do this, or give me a link of where I 
can find a manual for this?

Thanks a lot for all your help, I feel that we are getting closer ;-),

Dirk
