Has anyone tried to get SiN Gold running on Linux?
I believe there are numerous problems with the original Loki port on modern (64bit) systems, but maybe someone has gotten it running with one of the open source Quake 2 engines?

I played around with the loki version last year and if I remember correctly I got it working on 64-bit Ubuntu with the help of liflg.org and their installer.

Ritual Entertainment did release the source for the gamex86.dll (version 1.10) but not the modifications they made to the Quake 2 engine. I have never heard of anyone making attempts to adapt the open sourced Quake II engine to work with SiN.
