Thanks for the detailed information! Will try to summarize that for the 
FAQ.

ATI trying to fix fglrx for Wine sounds very good.

Concerning the bugs I observed (with Radeon HD 3850 and fglrx 8.11):

1. Prince of Persia SoT run with WINEDEBUG=+warn and minimum graphics 
settings gives
[---]
fixme:d3d9:Direct3DShaderValidatorCreate9 stub
fixme:d3d_shader:print_glsl_info_log Error received from GLSL shader #31: 
"Fragment shader was successfully compiled to run on hardware.\nWARNING: 
0:2: extension 'GL_ARB_draw_buffers' is not supporte"
fixme:d3d_shader:print_glsl_info_log Error received from GLSL shader #29: 
"Fragment shader(s) linked, vertex shader(s) linked. \nWARNING: 0:2: 
extension 'GL_ARB_draw_buffers' is not supported "
[---]
. The graphics error is difficult to describe; many misplaced 
offscreen vertices is the best description I can come up with (can take 
screenshots/video though if it helps).

In the meantime I also found http://bugs.winehq.org/show_bug.cgi?id=7411 
which looks like pretty much the same issue (see comment #8).


2. Supreme Commander supports shader model 2.0. Don't know if it uses 3.0 
features if present. Everything's fine until ingame; then, the engine 
seems to switch between the loading screen and a black screen. Same fixme 
messages as in PoP.


Can I help in some way? Trying patches, running other tests or games 
(e.g., Bioshock as a shader 3.0 game)? Is there some git branch worth 
trying out?
