That did help (a lot), now it is running on ubuntu 7.04 desktop with 
kvm-34 on kernel 2.6.20-16-generic. :) And what is more important, it 
feels a lot faster than the 'apt-get install' version.

I'll reinstall my entire desktop again some time this week and write up 
a tutorial on how to get KVM running with the latest version on your 
ubuntu 7.04 desktop installation (starting with the ubuntu cd).

Thanks,
Koen
