Your patch seems to work for 10-CURRENT/amd64.  I noticed no hickups with existing and newly created VMs, and the messages for loading the driver and network support stayed the same:

vboxdrv: fAsync=1 offMin=0x34da8a offMax=0x34da8a
supdrvGipCreate: omni timer not supported, falling back to synchronous mode
vboxnet0: Ethernet address: 0a:00:27:00:00:00

You were right about the device naming, I had to create a symlink.



I got another burp on the console.  ISTR that I got this one before, also, but am not sure:

I'll come back to you with results from testing on 7/amd64.
