VMware-Workstation 6.5

after I installed VMware-Workstation 6.5 I was able to use my existing VMs.
After a reboot I started vmware again and when I tried to open a VM, I got the error:

"could not open /dev/vmmon"

# /etc/init.d/vmware status
Module vmmon not loaded
Module vmnet not loaded

So I did a
# /etc/init.d/vmware start

and everything worked as before. Guess I have to do an insserv vmware to get vmware started at boot up.
