Re: [luau] pcmcia network cards and apm

[Warren Togami]

The Red Hat specific script I think depends on using runlevel 4 for
"suspend" mode, and runlevel 5 for normal operation.  You would need to use
"init 4" to put your computer to sleep.... not perfect but works.

Attached is the script that was posted to the acpi-devel list.
