Resume with ACPI doesn't work on ThinkPad R50e

[Marcin Jessa]

Hi again.

Actually setting hw.syscons.sc_no_suspend_vtswitch=1 seems to make resume not work.
hw.acpi.reset_video=0 is the only needed value. Then it's all fine.
The strange thing is setting hw.syscons.sc_no_suspend_vtswitch=1  manually with sysctl after the system has booted does not seem to have any effect.
It only disables proper functionality of resume after reboot.

Cheers,
Marcin.
