Yes...that would be a funny ad.
And it would definately be a positive thing for manufacturers to take note of this and begin to build drivers for Linux. With the Linux-using population growing every day, they can't ignore us forever. Intel may finally release some Centrino drivers for Linux.
Also, major game development companies will have a standard to work with. They can start porting their games over and writing new games for both Linux and Windows with more ease. If they keep a forum (as most do--bioware, most notably) for support, any finicky things that come with some distros or whatnot can be solved by the userbase.
