I have 2 Myth frontend systems that I've brought up to 2.6.29, and had 
problems with both.  One is running nvidia 180.* drivers, but I think I 
that was a problem with the forcedeth networking drivers which I cleared 
up with the NAPI option.  I've still got compositing turned off, but I'm 
not sure that that's a problem.  It's running QT rendering.  Also on 
this system, I'm unable to rebuild LIRC for the lirc_imon driver.

The other system has an older card, so is running the nvidia 173.* 
drivers.  On that system I get 3.5 fps with compositing turned off, and 
1.5 fps with it turned on.  (Obviously something's wrong)  As for Myth, 
I forget the theme, but I believe it's GL rendering, and it looks like 
it's having unusably bad transparency problems.  The menus are faded, 
and I can't see the highlighting.  It's also not as intuitively usable 
as the G.A.N.T., so I can't watch a recording by feel, just get out.  I 
haven't yet tried switching the theme under 2.6.28-r4, so I either try 
the QT rendering or G.A.N.T. theme and work by feel.
