video driver - if you are a real-gamer, you likely will be using amd/nvidia blobs, as the OSS aren't (really) good enough, if you want all of the bells and whistles....the OSS drivers might (at least radeon/intel) be good enough for lighter game play, while nouveau will likely blow the big one. I know (personally) i probably won't have any serious issues with Nvidia (blob).
Kernel that changes - That shouldn't be a big deal, and it's not like you have to upgrade your kernel every five-minutes. I just upgraded my kernel, a few days ago, but before that had been using the same kernel for months ~ after all, you can have more than 1 kernel installed... it is easy to install a kernel that your distro doesn't maintain/provide updates for.
skipping audio - I assume you mean PA, as i don't get skipping audio with ALSA or JACK, in any application. But i thought PA 2.0 was supposed to have resolved a lot of the issues, like skipping, poor audio, etc?
WM/DEs that don't work - Don't use one if it 'doesn't work', or report the problem (bug). Stick with a WM/DEs that DO work.
But i think we will see some improvements to linux and our software stacks, with gaming becoming more popular on the platform. Hell, i am not even a gamer, but i intend on purchasing some games/titles when steam is available for linux, as i would really like to see it be a success/win.
