Ditto the Inspiron 8500 - no apic at all (which is different from known-broken, since nothing bad happened.)
For cleanliness sake it would be nice to have specific model info in the blacklist ("your hardware doesn't have a frobber" is nicer than "the frobber on your hardware causes your pets to catch fire"), but since the hardware doesn't exist anyway the end result is the same. (And the code is a lot more readable.)
Perhaps just a comment above those entries: /* Latitude C840 and Inspiron 8500 have no APIC support in hardware */
Eventually it might even turn into a proper whitelist/blacklist collection.
