However, in current systems a device is ready only iff the corresponding
sysfs tree has been created or a hotplug event has be launched, and that's
the one sane place where userspace can wait for "something". Drivers need to
setup the name of the sysfs classes, so if modules could <crack smoking> 
export some of that info to insmod maybe insmod could be taught to do wait
for things in userspace or wait for events coming from the $FOO.ko module

(ok, maybe ugly but sounds somewhat cleaner than just adding a
"sleep(magicnumber)" to insmod)
