I was working on getting bestcomm and fec working, but forward porting
my old 2.6.10 code to current is turning out to be more difficult than I
expected.
If you already have working code then I'll stop working on them.

Where are these patches?  I'm new to this list so I don't have much history.
Would I find these patches in the archive?

I agree completely.

My politics (at least for the 5200 stuff) is the boot loader should :
