If parts are only rated to 70C or so, then running them at 150 would seem to 
be asking for trouble. I'd think that if you designed a 70C part into an 150C 
environment you'd find a bunch of lawyers gnawing on your bones pretty soon. 
I'd design in a higher-temp part or use peltier cooling etc to get the temp 
in the right range for the part.

There are some things you can do to promote reliable operation under higher 
temperatures. The most important is probably to run at slower clock speeds.
