sorry, i was in a hurry, i really should have asked more specific
questions. yes, there is no makefile in the kernel sources and that
causes all make commands in the kernel source dir to fail (of course).

i have the sources for 3.0.6 installed and configured emerge to change
the symlinks on install of kernel sources.
but... does emerge delete the older makefiles? why would it? 

i hope there is a reasonable explanation for the makefiles
disappearing, i really can't use a failing HD at the moment.

well, i built the kernel i am running, is there a different way? :P
