For the debian directory. I cleaned up the gentoo rules, it's not widely
tested but looks like it's working fine.

Nice, I like the skip on ACTION!="add". :)
You may want to add:
  SUBSYSTEM="block", BUS="ide", SYSFS{removable}="1", GOTO="no_volume_id"

cause removable IDE devices causes hotplug events on open()/close(),
which gives a nice infinite loop.
