background:

with the ps/2 mouse there are always problems with pointer 
synchronization. so i generally use
usb tablet device emulation. BUT. usb emulation is resource intensive. i 
have a testcase with 64
VMs on a dual quadcore xeon and usb alone almost uses the resources of 2 
cpus. so i decided
to introduce an option for 'console-only' vms. but in that case i would 
like to have ps/2 mouse
also disabled in case someone has the wrong option and complains than 
that his mouse
is unsynchronized. so 'console-only' should be no mouse at all.
