Subject: [PATCH] fix extra BIOS invocation during resume
X-Git-Tag: firefly_0821_release~30568

[PATCH] fix extra BIOS invocation during resume

It causes extra moon icons blinking on x60, and breaks at least two other
systems.

During resume, we do not know that "reboot"/"shutdown" method was used, so
we assume "plaform" and call BIOS, anyway...

This is 2.6.21 material, and should fix 2 or 3 regressions from 2.6.20.
