hi there,

this panic has been reported beforehand. i'm also experiencing it when
powering on a new image:

panic: clone_create() on cdevsw without minor numbers
cpuid = 0

here's a bt:

vboxdrv.ko got loaded before starting X (using /boot/loader.conf). all ports
are up-to-date and the running kernel is in sync with the kernel sources.

right now i'm running r192089 (CURRENT) and virtualbox-2.2.2r19673.
