Also, if/when it's time to port, find the code and/or information you need at 
the time, and test thoroughly on the actual hardware. These things can usually 
be done on "anything", one way or another, more or less efficiently.

The only thing that's worse than missing support for some new platform is 
"support" that doesn't actually work properly. Lots of debugging fun to be had 
that way... :-)
