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.
OK, I'll look into this. It's odd, because conform was working fine at 32bpp -- when did you make these changes?

It was back when I did a mini-audit of the visuals being exported in several drivers before 4.3.0 (beginning of Feb.). Here's my original message about i830:

The thread started here where I posted my orginal list of visuals exported by some of the drivers:

There were fixes committed for a few other drivers as well.
Hmm. The code in the i830_span.c is definitely bogus. That's Jeff's comment, I'm pretty sure.
I'll fix it, and the other issues you raised.
