I don't have a lot of control over that. The current kernel merge
process means that the recent spate of changes can't show up until
2.6.21. This is not really a "bad" thing; it's a big part of the reason
why kernel stability has remained fairly decent. The rules for kernel
inclusion are basically this:
1. Fixes for bugs can be accepted at any time, and can be included where
it makes sense (e.g. a 2.6.19.x point-release). However these must be
strictly limited to fixes - no new features.
2. New features are accepted only during the kernel merge window, which
is a 2 week interval that opens shortly after each kernel release.
Anything missing the window has to wait until the next window, which of
course isn't until the next kernel release.
The merge window for 2.6.20 opened and closed quite a while ago. The
next chance will be for 2.6.21, which won't start until 2.6.20 is
officially released (which may be soon). The pvrusb2 driver has been
pretty stable and quiescent until December when all the FM radio support
work got underway. Nearly everything that's changed since then has been
in support of that new feature, so you're really not going to see any of
this in the kernel until 2.6.21 at the earliest.
The hacks for allowing "mplayer pvr://" could be viewed as a bug fix.
However there are also some other more pervasive changes which I suspect
would also be needed (thinking about all the VIDIOC_G_TUNER fixes).
Even _I_ wouldn't want to see that stuff put into an older kernel. So
it may be best just to be patient.
If you're not patient, well there's always the snapshots, or just build
the official v4l-dvb repository (which usually only lags the snapshot
releases on a scale of days rather than weeks or months).
