Hi, all--

I've been working on this port over the past couple of weeks...  I've
added a 'pc' platform, which supports 'floppy' and 'ram' startups.  Here's
a quick status report:

- I have a prototype 'floppy' startup which allows an application to be
written on a 3.5" diskette.  This is how I've been running the GDB stub.

- The GDB stub is about 75% in place.  It doesn't know anything about
threads yet, and some of the exceptions aren't supported properly.
However, the breakpoint exception, is working great.

- I've just yesterday been able to get the clock ISR to work, so the 
threading support is next on the list.

- 'make tests' works fine, but only the hal tests (intr, context,
and cache) have been ran.  I'm sure that context still needs some work.

I'm hoping to have the threading stuff figured out by the end of next
week--I'll post it as soon as I feel like it's usable!  Stay tuned...
