Id has released the Linux client for Quake 4:

I've got it working on FC4 on a DFI LAN Party 939 motherboard with nVidia
6800GT.
It's mostly playable, but the sounds of the weapons suck. I don't know if
it's the sounds in the game or the audio driver, but I suspect the driver,
as the game uses the same data files as the Windows binary, and all the
audio should be in there. What's been others' experience with this?
Here's the mobo specs:
