Oops, fixed now. Thanks for pointing that out, the line between sh and 
bash is (too) blurry on Fedora & friends.

list-devices currently only lists devices which support driver 
overriding[*], which is a relatively new kernel feature and would be 
missing from 3.0.76:

It might well be possible to fall back to the "old style" bind system if 
the kernel doesn't support driver_override. I've no immediate plans to 
look into that but lets just say patches would at least be considered :)
