From what I've been reading, adding that bang seems to help in some cases. Do you happen to know why?
Here's a post from Len Brown at Intel mentioning that particular command.

Thoughts?
Passing the "!" argument actually disables osi detection. I'm not sure why that was ever suggested. It may have had some functionality in earlier kernels. When "!Linux" is used
Code:
ACPI: BIOS _OSI(Linux) query ignored via cmdline
When "Linux" is used
Code:
ACPI: BIOS _OSI(Linux) query honored via cmdline
