I know that. Both ACPI and APM are not built-in the kernel, but are 
loaded as modules.
Never the both of them

I tried it, and it doesn't help. Also as I found this helps on laptops 
that cannot resume the display.
My display starts to work, but all I see is the last screen before the 
shutdown. Somthin like :
"Stopping all tasks ===============|" on a blank console screen.
I've tried both from X or from console. Also disabled Frame Buffer 
Support in kernel.
