Sorry, I'm a bit snowed under right now.
The code you are looking for is in sys/i386/i386/geode.c around line 185
You basically need configure the GPIO pins you want and add more
Poul-Henning Kamp | UNIX since Zilog Zeus 3.20
phk at FreeBSD.ORG | TCP/IP since RFC 956
FreeBSD committer | BSD since 4.3-tahoe
Never attribute to malice what can adequately be explained by incompetence.
