Jan-Simon,
Thanks for the dmidecode output.
Did the console dmesg ask you to send it because
of OSI(Linux)?
Do you notice any functional difference when booting with
"acpi_osi=Linux" (default for 2.6.22 and earlier)
vs.
"acpi_osi=!Linux" (default for 2.6.23 and later)
Also, please send me the output from acpidump.
Didn't notice any difference.

thanks,

This BIOS makes heavy use of TRAP's into SMM, Windows version-specific hooks,
and WMI -- all bad news for Linux.
But OSI(Linux) itself is a NOP on this box, since LINX is set and never referenced, per below.
LINX is not a variable, but a field in SystemMemory region. Thus it
could be accessed from SMM or EC firmware without us knowing that.
IMHO it is too brave to call it NOP.
Regards,
Alex.
