sample /sbin/hotplug script

I've been quite pleased to see many recent improvement in hotplug support ... 2.4 test11 is now hotplugging USB network adapters for me when I need that! And many other devices at least get their driver modules autoloaded (using modutils support) even if some devices still need hand setup before they're usable.

To make a long story short, if you'd like to try it out I strongly encourage you to put the attached shell script into /sbin/hotplug and see if it does the right things when you plug in USB devices or Cardbus adapters into your system. (And configure HOTPLUG; see its config.help for more information.)

The test11 release has hotplug support for PCI, USB, and also for networking interfaces. (Though I've not tested the Cardbus/PCI support myself, and know it can't support class-based driver binding without a small patch I'll resubmit.)

This script should handle all three. It's a start! Improvements should be easy enough ... :-)

p.s. I'm particularly aware of contributions to the Linux
hotplugging effort from Keith Owens, Adam Richter, and Jeff Garzik.
