Comment (by Bryan Kadzban):

 The rule's match is wrong, yes (it's matching both raw-disk-I/O devices
 and Firewire devices).  But I don't think that removing the rule entirely
 is the correct solution, as /dev/raw/ is supposed to be where the raw-
 disk-I/O nodes go.  I think a better solution is to figure out an extra
 key to use so the rule only matches raw disk devices, instead of both disk
 and Firewire.

 Or, for the development book, to move to the udev-provided ruleset (we
 need to do that anyway before 7.0).  I assume they have this fixed; let me
 go check...

 Yes, it looks like the udev sample ruleset has a SUBSYSTEM=="raw" added to
 that KERNEL=="raw[0-9]*" rule (probably to prevent the Firewire match that
 you're seeing).  Does it fix the problem if you recreate that rule, and
 add the SUBSYSTEM match to it?
