 That sucks and, at least theoretically, it doesn't look right, from the docs 
I get the feeling that glXQueryExtensionsString() should always do :-/ . 
Beryl does the same but even the latest Compiz doesn't and I'd be somewhat 
inclined to trust Dave Reveman more when it gets to such things. Does Compiz 
work for you with the same setup? If yes and it's using the same libGL then 
this is probably just a workaround for something.

 Looking at your glxinfo which lists GLX_EXT_texture_from_pixmap in both 
client and server strings but not in what glXQueryExtensionsString() says I'd 
try to blame your Mesa, but it looks recent enough :-/. Also, IIRC, at work 
with ATI+AIGLX KWin detected TFP just fine, I'll check again.
