You must add --with-core-mod and it starts to rip.
Vlad, I think configure should be smart enough to know that
selecting any modules should enable core, too. OK?

However, I noticed that 2.6.21 isn't supported yet (build actually fails).
I'll try to add support by Monday, for now latest supported kernel is 2.6.20.y.

Yes, it's a known limitation currently.
There are 3 possible work-arounds:
- remove the build directory and re-open it
- run
  >quilt pop -a
  >rm -fr patches .pc
  before second configure run
- add --without-patch to second configure run (only works
  if you did not change the kernel version to build for)
