I removed the alpha component from the visuals because the 32 bit span read function in i830_span.c doesn't read alpha from the framebuffer (it always returns 255). There's a comment there saying that it should work but doesn't. I think that should be fixed before advertising an alpha channel. Also, I changed the bufferSize from 32 to 24, so that should be changed back to 32 if an alpha channel is advertised.
Hmm, changing this back doesn't seem to affect the output from glxinfo:

'bf sz' is still 24, despite me setting bufferSize to 32 in i830_dri.c:
pConfigs[i].bufferSize = 32;
any clues, anyone?
