Unless you have 2 instances of QEMU running, no, you're not supposed to.

0 means kqemu is ok?

I don't think so. The way I see it, when I'm running _one_ instance of 
QEMU, lsmod lists:

kqemu                  43428  2

When I run QEMU with the '-no-kqemu' option lsmod lists:

kqemu                  43428  0

The zero represents the number of processes currently using the module. You 
will also get zero if no instance of Qemu is currently running.

i use suse 9.3 with kernel: 2.6.11.4 maybe kqemu don't support it?

Yes you are if :
 * one instance of qemu is running 
 * this instance was started after kqemu was loaded
 * /dev/kqemu is there and has correct permissions for the account you're 
currently logged in (it might have disappeared because of udev...)

0 means the module is not currently used (no /dev/kqemu ?)

To be on the safe side with kqemu, you can add the following line to 
your /etc/modprobe.conf (or whatever similar file for your distro) :
alias char-major-250 kqemu
The device file itself can be created in a very simple initscript...

BTW, qemu complains if it was compiled with kqemu support and can't use it for 
some reason ("Could not open '/dev/kqemu' - QEMU acceleration layer not 
activated").

Cheers,
