Curiosity is the very basis of education and if you tell me that 
curiosity killed the cat, I say only that the cat died nobly.
- Arnold Edinborough
>Environment:
        
        
Architecture: x86_64
Machine: amd64
>Description:
Suspending a lenovo T61 works fine (with sysctl).
When waking it up, the status lights look ok, but the builtin screen
stays black, even after 'vbetool post' or increasing machdep.acpi_vbios_reset
to 2.
Pressing the power button afterwards leads to an orderly shutdown though
(no fsck after reboot), so perhaps it's only the screen that's missing.
>How-To-Repeat:
Suspend a lenovo T61.
