That's certainly nice to have as an option, but so are MacOS-hosted  
tools.

Based on the information at <http://okmij.org/ftp/xPRAM.html> (some  
of which is wrong) and some experimentation, I'm able to read the  
extended PRAM, and I've added a read-only /sys/mac/xpram file to Lamp  
(Lamp ain't Mac POSIX), my Unix-like environment for classic Mac OS  
(like MPW, only much better).  In other words, I have working sample  
code for reading the xPRAM (and writing it is almost identical).
