  i'll bring out that gun if i have to, so far so
good with the masking the scanner approach.  the
keyboard hasn't dropped all afternoon *knocks on
wood head*...

  my previous searches for help on-line didn't
get me far because i was using powerd and power
instead of autosuspend.  when you're not sure if
the problem is the kernel or the device it's 
hard to know what to search for first.  :)
