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 ;)
