Patched DSDT with additional debug info in _STA method of parallel device

BE CAREFUL!
This is for Milisav's machine only.

Milisav, can you download the file to e.g. /etc/DSDT.aml
and let ACPI_DSDT="" point to it, e.g.: ACPI_DSDT="/etc/DSDT.aml"

Then invoke mkinitrd and boot with an addtional boot param:
acpi.debug_level=0xF

You should then see a line in dmesg:
_STA of Parallel device
and another one following which is the interesting one.
Please also send some lines of dmesg around these messages, so that we can
check about at what time _STA is invoked.
