Hmm; that is odd...

No; if the driver didn't load that's a major problem.  Remember that if the 
channel doesn't exist all the subsequent channels "move up"...  serious 
potential security issues.

I'd rather have the system as it is, where it fails out with an error that is 
easy to understand so I can fix the problem.
