Should be very easy, as it's essentially just an 8 bit value for each 
"lamp" you'd like to control which directly drives the lamps intensity.

As Jacob explained it's an 8bit serial protocol which modern lighting 
equipment unterstands. However you need not know the details of this if 
you're just going to drive some dimmerpacks via DMX. If you really want 
to know the details look at:

I would suggest this one. It's cheap, supported and plug'n'play.
A Linux 2.6.x version of dmx4linux will be out in the next weeks.
