I managed somehow to succesfully resume laptop from suspend,
setting hw.acpi.osname="Windows 2001"
but lcd output is off and can not be turned on.
sysctl hw.acpi.reset_video=1 does'nt work, instead to resume, machine
remain in unknown state, keyboard input doesnt work.

Also if powerd + cpufreq combination is used, some time after resume
system will reboot itself:

Do I need to build/install UP kernel, or I can use SMP one with smp
disabled via loader.conf?
