Since we merged a kms driver for Intel hw that supports all intel chipsets
and more importantly all the outputs on Intel chipsets, intelfb should
be considered legacy at the least and broken on > 50% of intel hw.

We left it in in that most ppl who wanted it were using it in embedded 
configs, whereas for most users it just doesn't work, like I don't thinkit
supports LVDS which means loading it on a laptop will trash it.
