Works for me so far:
https://github.com/blitz/freebsd/commit/cdc5f872b3e48cc0dda031fc7d6bdedc65c3148f

If anyone wants to test this, use any recent qemu with KVM:
wget http://os.inf.tu-dresden.de/~jsteckli/tmp/mfsbsd-kvmclock.iso
qemu-kvm -m 1024 -cdrom mfsbsd-kvmclock.iso.

and watch for

KVM-style paravirtualized clock detected.
Timecounter "KVMCLOCK" frequency 1000000000 Hz quality 1000

in the kernel log.
