That works, just don't run multiple copies of this script at the same
time, you'll hit race conditions in the 2.4 kernels which will hang or
panic your system.  It doesn't deal well with one process trying to
add a device, while another process tries to delete the same or an
adjacent device in the device list.  This is resolved in the 2.6
kernels.
