I'm using the same Gentoo ebuild, but with a 2.6.15-r1 kernel and  
ivtv 0.4.2, and it seems to be working.

You didn't mention your CPU (I'm using an amd64), or what capture  
card, but  ivtv is known to be sensitive to kernel version and ivtv  
version. You want to watch module versions, there are some that are  
provided by both the kernel andivtv, and if you;re using a recent  
kernel you want to use the kernel-supplied modules.

You might want to upgrade both the kernel and ivtv, since you are  
going want to do that eventually anyway. It might solve your problem  
and even if it doesn't you will be fighting more recent stuff :-)
