Hi. I'm currently running several games that may meet your criteria.
I've got PF JAGSS, a Pathfinder/D&D 3.5 exploration game. If you aren't familiar with Pathfinder, don't panic. It's just an extension of 3.5, but if you want to stick with purely 3.5, that's fine by me.
Here's the link to JAGSS:

I'm also running a steampunk game set in Victorian times (1899).
I may be starting a new Iron Kingdoms game, using 3.5 rules. It's 'full-metal fantasy'--essentially steampunk fantasy--a mix of medieval magic and firearms.
