(just guessing!) hw.acpi.osname is for \_OS and it does NOT influence \_OSI at all. They have totally different semantics although MS is advocating \_OSI is some sort of improved version of \_OS, unfortunately. Some BIOSes use both \_OS and \_OSI (e.g., \_OS for old Windows and \_OSI for newer Windows). Because of this problem, ACPICA just matches any known Windows OSIs for maximum compatibility. :-( FYI, in the latest ACPICA in CURRENT, we can install or remove OSIs from OS but the FreeBSD part is yet to be implemented.
