Mark-

You don't have to worry about this... Since ivtv is an out-of-tree 
kernel module, and 2.6.15 is not released to mainline yet, so you cant 
expect the distros to make their external driver packages compatable.

Anyhow, I believe that ivtv 0.5.x is meant to be built against 2.6.15 
...  We have been merging some of the modules from ivtv into v4l, and 
some of those modules have already made it into 2.6.15.  I think you 
will run into module collisions using ivtv 0.4.x with kernel 2.6.15, but 
i'm not sure about that.  Please see the ivtv mailing list / web site 
for more information about this, and how to get it to work with your kernel.

Eventually, the ivtv driver will entirely be merged into v4l (and the 
kernel), and things will be much easier.  Until then, you should try the 
new 0.5.x version of ivtv with Kernel 2.6.15

Cheers,
