3D support is actually quite important for many folks, if you don't need it
you can just use the "vesa" driver with either ATI or Nvidia.

Because our kernel doesn't yet provide all the features the driver needs.
I've added some of them, but mroe stuff is needed.  Nvidia sent out an
e-mail a while back listing the things they need as far as kernel support.
Given their willingness to do a driver and my interactions with both
ATI (in the past) and Nvidia, I'd say that Nvidia supports FreeBSD much
more than ATI at this point.  Note that ATI only opened up their documents
for the older R2xx cards under an NDA to developers working for a company
that was under contract to develop a driver, not out of the goodness of their 
heart.  To my knowledge, Nvidia is not providing a FreeBSD driver due to a 
commercial contract, but closer to "out of the goodness of their heart."
