What's the proprietary module that's tainting it?  Ideally we'd like to see it 
reproduced on an untainted kernel, but depending on what it is, it may not matter.

When you say you're not able to log in, is that because the keyboard is 
unresponsive?  It appears to be affecting USB, so I'd be curious to know if you 
can ssh into the box, or log in with a PS/2 keyboard.  Of course, some PS/2 
ports are connected via USB under the hood, so the keyboard might not tell us much.
