I use qjoypad (https://github.com/panzi/qjoypad) to configure each shift to a single number press. So for example shifting into 2nd gear sends a single "2" key press to Linux.

After that, I usual xbindkeys & emacs to configure more complex bindings. So for example "WindowsKey + n" is configured to go into workspace n. Or "CapsLock + 8" is binded to close the current tab I'm on.

You could improve on this using F13-F24 as they're pretty much universally supported by X, SDL, etc.
