Hmm thats what I said to pete before the depmod he added to the kernel-ebuild
does not work.

Do you have /lib/modules/2.4.0-ac11/modules.dep?

If so take a look into it.

There muste be some wrong path's tha point to /lib/modules/2.4.1-pre8

change them to .../2.4.0-ac11 and rerun

depmod -a

then things should worke fine again.
