Seriously reading some of these comments makes my head hurt... even if valve does port the source engine and their games to linux, that's only a handful of games... Most developers are still not going to target linux because it's painful to develop games for* and the market is relatively tiny.
*I've never developed for linux but from what i've read the summary is: video driver support is a mess, low-level access to hardware often requires hacky work-arounds or is just not possible, and of course there is lots fragmentation with having different distributions which just adds to the already painful fragmentation already faced by PC devs with having to support lots of different hardware.
IIRC in order to make the acceleration work correctly nVidia needed to actually re-implement a number of parts of the X Server itself since X was not originally designed for accelerated drivers / compositing.
