Adove patch works well :)  Now I can load kqemu and run
qemu with it!  I guess it should be under files dir of
emulators/kqemu-kmod.

And another problem comming X-(
After startup WinXP on qemu+kqemu, at user logs in,
qemu gets Segmentation fault.  It looks like fails
at the same point always.
Any one have any ideas?  Someone have the same situation?

Thanks
