Does 2.6.25-rc1 work for you? That's the first broken kernel I've reported for 
the radio application?

There are three patches that are meant to fix the bugs with radio. On the tests
I did here, they worked, but the Bongani still points that the fixes didn't
solve for him.

On the tests I did here, the three patches seemed to work [1]. Maybe you could
test with those patches and post us some results.

There are three patches meant to fix several issues caused by the conversion:

Could you test please and give us some feedback?

[1] Yet, I've discovered recently that the hardware I use for testing PCI
devices is broken. Probably, my motherboard chipset is damaged, since I'm
getting intermittent bugs on several parts of the machine - even with stable
kernels - so my tests with bttv aren't conclusive.

Cheers,
Mauro

These patches fix my regression. Thanks!
(no oops, radio app does not crash/hang, no messages about invalid ioctls, i can hear the radio)

When you exit the radio application do you get an oops? And does your TV work 
with those patches? Those were the two issues I had.

I decoded the oops that I got and found that the cause was the 
miss-application of  Robert Fitzsimons' patch. On the git version that I had, 
the radio_release function was not on the lines on that patch (I just saw 
the .rej file ;)

Those patches brings back both the TV and radio functionality, the tv 
functionality loss seem to have been lost when radio_release oopsed and 
didn't decrement btv->radio_user

These two above fixed it for me too

I can't comment on this one since I don't use 32bit user-space

I confirm that those patches fixed the bttv-driver for me, it was the 
misapplied patch that caused the Oops. Please push to Linus and I'll ask 
Rafael to close the bug as soon as it gets to mainline.

Thanx for all your work Mauro and the V4L developers.

Linus already pulled the patches to mainstream, so, the bugs can be closed.

Thank you for your time reporting and testing the fixes.
