After some more checking - I guess this information actually is not useful at all :(. It looks like even when the suspend is succesful - the line: ACPI: PCI interrupt for device 0000:00:02.0 disabled is alway the last one visible.
I'll try to get figure out a better way how to invoke the lock.
And my graphics adapter is: 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) (prog-if 00 [VGA controller])
