Subject: Set the sleeping indicator light on machines that support it, in case SMI
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=1887d54eedeb151eb2321410a9034c10b93ef5d8;p=openbsd

Set the sleeping indicator light on machines that support it, in case SMI
doesn't do it for us. Shows the 'moon' LED on older Thinkpads when
sleeping.

Tested on T43p, W500, T510 by me and on X61s by deraadt@.
