It seems that you have a game that has problems with the gdi engine(or lack 
thereof): http://wiki.winehq.org/DIBEngine

How much work would this be? I know nothing about Windows or X11 programming, but is it something that I might be able to study up on and propose for a Summer of Code project?

For the past days, after Stefan pointed me to that bug and article, I've been trying to figure out what would be needed in order to fasten at least Fallout 2 up.

I haven't been able to pinpoint any call made by the game requesting an image from X, and it always blits the whole screen at a time. Doing 640x480 8bpp -> 32bpp seems to be the problem and the fact that it does as many as possible blits. Nor have I been able to find a call asking it to blend two surfaces.. Could someone give me any hints on this?

The 8bpp -> 32bpp conversion could possibly be optimized.. But I haven't yet looked at it.

A bit out of topic; playing fallout2.exe makes X11 grow much larger, and it doesn't seem to free the memory.

A SoC project sounds great!
