Hi Ed,

using the same steps you described, I can confirm this: I downgraded
from kernel-3.2.2-8 to kernel-3.3.2-1, rebooted to 3.3.2-1, run
"/etc/init.d/vboxdrv setup", removed kernel-3.3.2-8 and reinstalled
kernel-3.3.2-8. After this procedure the vbox modules for kernel-3.3.2-8
were correctly installed. This is really a hint that the problem mostly
lies in the kernel update and not in dkms.

I guess too.

Thank you for your cooperation.

Kind regards
