As you should. ;-)
If you're looking for an add-in card (i.e. non-Intel) with the best chance of having decent open source support, I'd recommend going with an ATI R500-based card. I've been able to get a very nice dual-head setup working with the radeonhd driver and my X1650 card. There's even a chance that it will have working 3-D acceleration someday.
