Hi Sascha,

I've been following this whole process for quite some time now and also 
tried to help out. I've come to the conclusion that it is purely due to  
bad chemistry between various personalities. Technically this stuff 
should have been merged a year ago if not earlier. It is really sad, 
but it happens sometimes. There also isn't one person to blame, 
it's 'just' personality conflicts that caused this mess.

It's my conclusion that in the interest of the end-user Markus' approach 
is probably the best. Not technically the best: that would be if 
everybody got their act together and just worked towards merging it 
into the kernel. I've looked at the code and I think with perhaps a few 
evenings of work and everybody behaving reasonably it could be merged.

But the end-user couldn't care less about this situation and just wants 
to have a working driver. Perhaps in the future when different people 
step in this might be resolved better.
