Oh good, I thought I was the only one doing that.

The reason I don't like udev is that it's just to slow; something like a 5-10s 
delay on each boot.  No idea why it should be so slow, but it's probably 
probing the kernel for all available devices at boot, when it could be much 
quicker by probing for the device on access.


Thanks!
