Hehe, no you won't get such pleasures from me!

Anybody who provides Open Source contributions deserves an exceeding 
amount of respect.

OK, good! I have a starting point.

Is it safe to assume that I can post reasonable questions about the 
Makefile dependencies as I go along, if necessary?

I will do my own research, but I think I will have a few questions along 
the way.

Good idea.  Very good idea.  I will start with an existing driver make 
and compare it with GEODE.

Cool, makes perfect sense.  Obviously I haven't read all 1000 pages of 
the GEODE handbook. :)  Also
my board mfg didn't provide this little detail.  Thank you! :)
