I've been able to verify that Chromium does not use RENDER acceleration
for antialiased fonts for web content; I asked one of the developers.
That would seem to explain why it doesn't show up for Chromium web
content (as stated in my previous comment).

I believe this is a bug in EXA RENDER acceleration on the Radeon RV100.

 "Extra efforts should be put into getting EXA issues forwarded upstream."  ... 
I'm hoping my hunches/semi-educated guesses here fall under "extra efforts".

Cf: http://lists.freedesktop.org/archives/xorg/2006-July/016661.html --
this sounds like the same issue.  Note that "Despite the name (rv200),
[the Radeon 7500 is] r100 based."
(http://dri.freedesktop.org/wiki/ATIRadeon#head-
9161ac9470497d94f1a4f79794697347b20d5170).  That report is from 2006.

I could swear I was looking at a blog post on the commit of EXA RENDER
accel support for Radeon the week before last, but I cannot find it now.
I'll keep poking; it seems RV200 and RV100 and programmatically similar,
and I'd like to ask if it was ever tested on RV100.
