Who told you Linux doesn't work? worked fine for me, it has native 32 and 64 bit linux support.
As a linux player i always load the maps faster than everyone else.
So actually I still use 10.4.11 and FF3 to play Quake Live on my MacBook and it runs flawless with my normal Set up for more FPS and about Linux so and OpenSUSE It also works flawless so far haven't had any troubleshooting with any of those OS's only my Internet does hate to play Quake Live -.-''.

I was struggling so much with my Mac that I installed Windows 7 on a partition. The difference is like night and day. Windows 7 handles the game so much better in every way. All the features in the browser and game work correctly. But most importantly and this shocked me quite a bit. I was getting 60 - 70 fps on every map using the lowest video settings with my Snow Leopard. In windows 7 I'm getting 125 fps constantly using the highest video settings possible. It's beyond smooth. Anyways, I just wanted to post an update.
