Cannot open AMP device: File exist

[Katsumi Matsumoto <kmatsumo@charybdis.princeton.edu>]

I am trying to put my powerbook g3 (wallstreet) to sleep but seem unable 
to.  

For both "apm -s" and "apm -S" at the command line, I get: 
"Cannot open APM device: File exists"

Also, when I just type "apm", I get: 
"32-bit APM interface not supported".

I am able to use xapm though, so something works.  I'm pretty new at this 
and would appreciate any advise.

Thanks in advance.
