[PATCH RESEND] ACPI: Add Toshiba NB100 to Vista _OSI blacklist

[Levente Kurusa]

This patch adds Toshiba NB100 to the Vista _OSI blacklist.

The _OSI(Windows 2006) method is bugged on the netbook resulting in messed up
PCI IRQ Routing information. This was observed on a netbook,
whose SATA controller mode was set to Compatibility mode.
The driver would then register itself to IRQ#16, but the device
was in fact issuing interrupts to IRQ#20.
No side-effects were found during testing, everything is
working as it did before.

That should be in linux-pm/linux-next already, isn't it there?

Hm, I didn't receive any reply back on the other mail, so I thought it got
lost somewhere. I see now that it has been applied, thanks and sorry for
the inconvenience.
