I'm working on a site that still has a lot of scripts in ColdFusion. I need to move it to a new server. I much prefer Apache/Linux instead of IIS/Windows. I've seen some info here and there about running ColdFusion on Apache/Linux. Is that a stable setup?
It's perfectly stable. I ran a hosting company with ColdFusion 4 through 6.1 running first on Fedora and later CentOS. I used to work for Nationwide and deployed a major application there using ColdFusion 6.1 and later 7 of Red Hat ES.
I've written an extensive article on what you'll run into when moving a ColdFusion application from Windows to Linux.
You can find more info about running ColdFusion on Linux here or by searching ColdFusionBloggers.org.
