Medion Akoya 1210: BIOS _OSI(Linux) query ignored

Hi,

the "Medion Akoya 1210" is a re-branded MSI-Wind U100, it seems the ACPI is not supported correctly. I get the following message
in /var/log/messages.

you can ignore these messages.
they are deleted from the latest kernel.

(unless "acpi_osi=Linux" actually makes some functional improvement
on this system)

thanks,
