Strange, fallback code should work OK. I'll test it

I'm not sure that it's a good idea. At least - moddb may be leaved for 
user drivers/fresh versions of drivers.

Currently we:
0) probing drivers from initmod
1) trying to probe drivers from moddb
2) trying to probe drivers from sqfs and copy missed drivers to /lib/modules
