Thanks Rob.  I build mythtv with your new ebuild but I still don't seem 
to be getting ivtv support.  Is there something I need to do with my 
kernel?  I verified that the v4l2 modules are loaded:

mythfe01 layman # lsmod | grep -i v4
v4l2_common             8493  7 
videodev               70485  8 

Here's the beginning ouput from 'emerge -av media-tv/mythtv' that show 
no ivtv support being built:

[ebuild   R   ] media-tv/mythtv-0.24_p20110410  USE="alsa dvb dvd lirc 
perl python (-altivec) -autostart -bluray -debug -experimental -ieee1394 
-jack -lcd -profile -vdpau -xvmc" INPUT_DEVICES="-joystick" 
VIDEO_CARDS="nvidia" 0 kB [1]

Total: 1 package (1 reinstall), Size of downloads: 0 kB
Portage tree and overlays:
  [0] /usr/portage
  [1] /var/lib/layman/MythTV/Gentoo

Would you like to merge these packages? [Yes/No] y
