Well, Ian Campbell's version of the ivtv_xdriver compiles, builds, and runs 
just fine for me.  The problem I have is with the ivtv_fb.ko module.  It 
loads without any errors, but TV-Out remains a blue screen in 0.9; unlike 
in 0.8 where upon loading ivtv_fb.ko, which happens long before starting X 
and loading ivtv_xdriver, the TV-Out signal drops from blue to green to 
black.  That does not happen with 0.9's ivtv_fb.ko, it remains at its 
initial power-up state of solid blue.  I can see from Xorg's logs that it 
starts up and apparently continues to run fine, thinking that there's 
nothing wrong with the framebuffer, except that nothing actually appears on
