[mythtv] Framebuffer number query failed

I just updated my system from FC6 kernel 2.6.20-1.2962.fc6 to  I also did a "yum update" to get any updated IVTV 
packages from atrpms.  After a reboot, I tried to watch previously 
recorded programs and received the following error in the mythfrontend 
log.  Things seem to work if I go back to the 2.6.20 kernel.

Is there anything that I need to update to correct this error?
