It works with 6.3, 7.0 has the ULE scheduler which doesn't have sched_lock.

Rink@ has been trying to get it work on 7.0, but...
"<rink> Mavvie: haven't gotten it to link yet :-/"

It works on 6.3, until you try to start the VM:

With VBOX_SUPLIB_FAKE=fake set you get:
    VM creation failed (GVMM).  VBox status code: -37 (VERR_NOT_SUPPORTED).

Without it (i.e. using the "kernel" module):
    Failed to load VMMR0.r0.  VBox status code: -609 (VERR_SYMBOL_NOT_FOUND).

And the documentation about the kernel module as described on
http://www.virtualbox.org/wiki/Porting_VirtualBox are lacking a bit
of essential information.
