Evergreen / radeon:
release: sept/oct 09
modesetting (KMS and UMS): beginning of February, ~4 months
Fermi / nouveau:
release: Nov 09. Huang said so. Ok, let's make that april 2010.
modesetting (KMS only): now. ~4 months.
AMD spent additional time on IP review and they wrote extensive documentation while they were at it. Their task was more difficult this time since they had to deal with huge changes in the display logic due to Eyefinity.
Nouveau spent additional time RE'ing the cards. Their task was easier since they skipped writing UMS code and the display logic should be similar to the older cards. They can also blindly copy what the blob does, they're not required to understand and document it.
So as we can clearly see, both apples and oranges took around 4 months to develop.
