When I use your config-2.6.36.7 file on 2.6.36 and run 'make oldconfig',
I don't see anything like changes in disk or graphics card drivers and
I don't see 100 or more lines thrown away in the multimedia drivers.

Did you use 'make oldconfig' or did you use that script that you have
mentioned and posted in the past?  Could it be causing problems?

Curiouser and curiouser.
I always download & build from .bz2 tarballs, with no problems.
