[gpm] LED blinking hooks

[Ben Liblit <liblit cs wisc edu>]

Two small scripts are attached to this message.  I place these in the 
"/etc/pm/hooks" directory on my ThinkPad X40.  They cause my laptop's 
crescent moon LED status light to blink during preparation for suspend 
and recovery after waking back up again.  I like them as a nice 
indicator that things are in progress.

Gripe: the unfortunate names are necessary because pm-utils already 
installs hook scripts named "00NetworkManager" and "99clock".  This 
makes it difficult to have other scripts that go before the former (or 
after the later) while still using only two leading digits.  IMHO, 
pm-utils should use less extremal numbers for these two scripts.

Caveat: LED 7 is the sleep (crescent moon) LED on my ThinkPad X40.  It 
may not be the same LED on your laptop, especially if you are not using 
a ThinkPad X40.  I doubt that there's any risk of *damaging* your laptop 
by asking it to blink LED 7, but laptops are fickle creatures.
