the problem really is that 2.6.18 isn't 2.6.25. OSI("Linux") is really
the wrong thing to do!
Not even microsoft does that.. they have very version specific OSI
strings.

Can you work with your colleges in the BIOS team to make sure that no
future BIOS will use OSI("Linux") please? If there's something they
would want to disable because of a Linux bug.. the real solution is to
fix the Linux bug!
