what is unmergeable?

There were discussions since the beginning of 2006 which lead nowhere.
It finally turned out to be a personal issue between developers and to
stop those useless discussions and to not having to rely on an
incomplete API and not having to strip off the sample drivers the
alternative way was developed.

ahm, there are more problems than you might think about...
* broken drivers (eg saa7115, incomplete driver tvp5150)
* limited API which is managed by a few (DVB/V4L)
* having to deal with people who disagree alot

I submitted the patches RFCs and didn't get proper comments back then
this doesn't motivate me in any way to continue the work and spend any
efforts in getting companies to release their sample drivers.

As pointed out it's possible to release the complete driver in
userland even as binary driver if someone wants to, unless someone
kicks out usbfs. But the conversion would take a while. And regarding
the plans of the other drivers I pointed out what my plans are.
