I have a Dell Latitude and:
dmesg | grep i8k
i8k: unable to get SMM BIOS version
In my case the dmesg output is the same. But this doesn't stop i8k from loading even without "force=1".
Also have a look at
modinfo i8k
Although I haven't "played" with any of the options.
None of the options seems to be relevant. One can force loading without recognition of supported models but cannot force supporting unsupported ones :(
