mythtv problem with kernel 3.4.2-1.fc16.x86_64

I've mentioned this in the 'ATrpms Status Update' thread and on the 
MythTV lists, but an update seems better in a new thread.

Under 3.4.2-1 I find that mythtvsetup doesn't recognise any of my tv 
tuner cards.  I do have recordings made with this kernel using settings 
set up under 3.3.7-1 but some have failed. I have not seen similar 
failures under 3.3.7-1 either before or after trying 3.4.2-1.

dmesg | grep adapter shows that all the cards are registered by both 
kernels.

Although I believe that all my cards now have in-kernel support, I 
wondered if this problem was linked to my not having video4linux 
packages for the new kernel, so I used the media-build script to create 
something similar. ( http://git.linuxtv.org/media_build.git )

It made no difference. 3.3.7-1 works for me, but 3.4.2-1 does seem to 
have brought problems.

I'm using nVidia 295.49 with the earlier kernel, and both 295.59 and 
302.17 seemed ok with the newer.  All these are from packages now or 
formerly in the ATrpms repo.
