Well for those following along and catching this from google and what not,
i've identified a solution to this. If you are using mesa 7.3, you'll need
to add this commit from mesa git:
+ From 529d1d720e1422bad1880ef33fae1c9423112d2e Mon Sep 17 00:00:00 2001
+ From: Eric Anholt <eric@anholt.net>
+ Date: Wed, 04 Feb 2009 03:29:11 +0000
+ Subject: swrast: Add support for x8r8g8b8 fbconfig.
+
+ This lets swrast produce an fbconfig suitable for the root visual now that
+ the server's not allowing mismatched fbconfigs.
It's not currently targeted at release 7.4, but I proposed it get added.
Regards
