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
