Have a look at this piece of code if wrote :
http://vitsch.net/cgi-bin/gpl/cat.cgi/lampd/v1.0?lampd.c
It's a very small udp network daemon to control my roomlights over the LAN.

Basically you need to open /dev/io to get io read/write permission, after that 
you are free to bang all IO-ports you want.
