I actually play AoS on Snow Leopard using a Wineskin wrapper + ie7 (gross, I know.. but all AoS games are launched from the browser and FF didn't work right for me..)
If you're familiar with wineskin, the process was something like:
1. create new wrapper
2. in advanced settings, launch winetricks and install ie7 (ie8 is always weird/crippled for me)
3. set homepage to http://ace-spades.com
4. in OSX, download the AoS installer MSI
5. Install the MSI from your Wineskin wrapper
6. Set the ie7 bin to be the "start program" for your wrapper
7. Launch the wrapper
8. Click game
9. Profit!
