Please report in the qemu ml, I probably don't have the time to hack the glue code . Keep in mind that kqemu is a proprietary software.

This whole thing is due to a renaming in some kernel functions from kernel 2.6.12-gitX on (and mm-sources are using a very new kernel-version). A similar problem was fixed by a patch in http://bugs.gentoo.org/96449
Created attachment 62514 [details, diff] Patch which fixes kmod.c This patch will fixe the problem so kqemu inserts fine with my new kernel. ebuild follows.
Created attachment 62515 [details] Ebuild for qemu-softmmu This is the ebuild taht uses the patch posted above. Emerge qith USE-Flag "newkernel", so the patch will be applied.
I guess that there is a simpler solution, add some ifdefs in the patch. Keep in mind that kqemu isn't opensource, I should ask the upstream author before changing it.
The patch is rejected, you NO-OP the sysfs support. The problem is due my sysfs support patch so I guess I should do something about that myself.
Anybody who is willing to create a fix for kqemu 0.7.1?
qemu-0.7.1 works if you remove the sysfs patch
Maybe a sysfs USE flag should be added to the ebuild to include optional support for sysfs? And print a warning that support is broken if kernel >= 2.6.12 ?

The issue should be solved, isn't it?
