Thanks for the acpidiump output.
acpi_osi=Linux is a NOP on this box.

It looks like Dell went out of their way to make Linux a recognized OS,
but the code that actually accesses TOOS makes Linux a synonym for Vista,
which we have w/o OSI(Linux). The exception is the PCI root bridge HID/CID
exchange, where only Vista gets PCIe native.
