i realize this is a pretty vague description, but i haven't had the time to track it down more specifically yet. i will look at it more closely as soon as a i can.

Additional info:
* kernels 2.6.28.2 - .4 (using the abs kernel26 PKGBUILD and the kernel26-vanilla and parallel PKGBUILDS for me)
* pacman 3.2.2-1
* fakeroot 1.2.1-1

Steps to reproduce:
run 'makepkg' against any kernel PKGBUILD that calls 'make {x,g,menu}config'
