You will be interested by egl-dri see on freedesktop for egl mailing
list archive. It's not right now usable with any dri driver but you
could expect a radeon r200 support soon (IIRC Dave is working
on that). Meanwhile Jon Smirl done the fbdev support for it,
it should be operational though i haven't get time to test it.

See http://www.khronos.org/opengles/spec/ for egl description &
that draft of egl mesa extension in egl-dri mailing list archive.
 
If you can't wait you can try miniglx see www.mesa3d.org but
i am not sure that it isn't broken right now...

Maybe if i get little free time & if no one do it before me (read please do
it before ;-)) i will add egl support to r300...

Sorry but what is exactly xen (googling give me pointless informations
i think...). :)
