I can neither confirm nor deny that your unit will work, because (as 
I've written earlier) I use my own v4l2 unit and also I don't have any 
v4l1 device.

If you want to test a distro with an up to date kernel, then you should 
try ArchLinux as it uses a rolling release like Gentoo does, but without 
the "compile everything yourself" concept ;)
