I'd wager a guess that there is no actual hardware Falcon with AB040 that runs 
Linux out there - Petr had trouble getting Linux to run on that hardware and we 
never got to the bottom of that. 

The amount of TT RAM might be an additional clue. 

If that's not enough we could conceivably detect usage of natfeat drivers in the 
running kernel, and modify the /proc/hardware output in that case (perhaps 
enabled by an additional kernel boot option flag so we won't affect other uses 
of /proc/hardware). 

Placing a flag in the kernel boot option seems like the easiest way to signal 
the kernel runs on an emulator - unused optios should be passed to init which 
ought to ignore an option like 'aranym'. Please try that. 

Cheers,
