Hmm...this doesn't look good to me. IMHO, my old patch works better.

What I was considering is to add `options ATI_BROKEN_FONTSEL' (or
better name) to config files and make the patch compilable optionally
for ATI users. The patch doesn't do any harm to non-ATI graphics cards,
just making screen switching a bit slower. A number of people 
reported me that it worked fine.

If you're okay, I'll commit my patch.
