Just thought I'd update this. I found a ZIP of the last 32-bit supported Chrome from Collin's webserver (dosdude1).
There's lots of other useful stuff in there as well at the parent directory, and on the home page as well. Updating this mostly because I came across an Early 2006 17" iMac sitting in the recycle pile at work. Dug it out, put Snow Leopard on it and it works great! I'm mostly using Firefox 45.9.0 ESR on it as it was the last supported mainstream browser I've found for 10.6/32bit. Just stopped this year since it was an ESR release.
