It's almost certainly only 3000 series that's interesting; I think they 
test the Thinkpads with Linux and wouldn't ship with a quirky BIOS there. 
The 3000 series only officially supports Windows, and so there can be 
problems (evidently, mine does something odd with the legacy mux, and 
newer ones do something odd with the active mux).

You might want to poke at the quirk in the patch in this thread and see if 
one or the other mode works better, or if they're the same on your 
machines. In any case, neither the patch that got into 2.6.25 nor the 
narrowing patch in this thread would affect either of your machines.
