Before I switched to linux, having the PICDem 4 powered off the ICD2
worked fine, and I havn't added anything extra to the PICDem 4
prototyping area, so I can't see a reason it won't work now, unless it
cannot power the target board when connected via serial to the
computer.

My main problem at the moment is how to enable powering the target
board - that option is off by default, I think.  How do I turn it on?
- I have read the man pages for most of the GPUTILS and LPLAB
programs, and none of them seem to be able to configure the ICD2.
