Ok, I have an initial pkgsrc package at 
http://www.ecademix.com/JohannesHofmann/tmp/kqemu.tar.gz

Some issues I came across:

* I had to remove the '-nostdinc' when compiling the common directory
  (patch-aa). Not sure if that is ok.

* To build the actual kernel module I needed to use DragonFly's make.
  I forced this be calling /usr/bin/make which might not be the right
  thing to do.

* The module is installed to /usr/pkg/lkm/. This is copied from
  emulators/vmware-module. Again not sure whether this is the right
  thing.

Cheers,
Johannes
