The point is that the feature they removed is of very limited use since only
a very limited amount of users would need / use it anyway (quad head monitor
setup combined with two GPUs running SLI mode).
Most peoples (including me :) run at a max 2 monitors or may be three
monitors.
Unless extreme multihead configurations are your core business (e.g. Matrox)
this means additional man power / QA activities to make this work in the
"real world" plus there is currently no intel-based solution to provide quad
head monitor setup with fully free drivers without hickups.
So IMO peoples need to be quiet......
Especially since Noveau (be informations available from NVidia or not) will
have a hard time supporting SLI modes for a large variety of GPUs plus quad
multihead setups.....
