I just posted an updated version of a Dependencies install script, for 
fedora 10 and svn, on the mythtv wiki under Howto -> Dependencies 
(Building from Source). It makes building a new install rather easy.


It probably works for .21 and .21-fixes too, as it just uses yum to 
install packages for myth (and mytharchive, mythmusic and mythvideo). 
There are 123 listed packages including kernel-headers and such which 
will pull in and install the OpenGL glue which might be missing for your 
(new) kernel. (There 2 packages which I think have been subsumed into 
something else as I cannot find them in any repo.)

I don't know that it will help your problem but it might.

Two questions however:
  Did you check that /usr/lib/qt4/bin is installed *before* 
/usr/lib/qt3-3/bin in the PATH of your mythfrontend user?

And do you have Composite Extensions disabled in xorg.conf. I think the 
latter 'on' is a killer for OpenGL.
