Uh, no, this doesn't help :-(

Half-life supports only 16bpp(well, I can set it to other values with regedit, 
but it seems to have no effect), fglrx supports 24bpp only.

I switched to the Xorg radeon driver which has 16 bpp support(the 2nd column 
shows 16 now), and made sure that hl runs with 16bpp, but the error still 
occurs.

The opengl output is now:

But even if it worked this way, this wouldn't be a good solution for ATI 
users, because playing newer games with the "radeon" driver is horrible.
(e.g. Jedi Academy, gl-117, even tuxracer makes problems).

Removing the failing check from Wine's opengl code doesn't help, it causes a 
hard crash later.
