Corsair K90 G keys in OS X?

Wondering if there's a practical way to program the left G Keys in OSX.

I know that since the keyboard has onboard memory for the macros it should work - once programmed in Windows - in OS X. But the Mac I'm hanging it on isn't boot camped - and I don't really have plans for it either (plus having to crank it up every time is annoying). A Fusion VM image was considered but I've verified that the drivers won't install on a VM.

I do run Keyremap4Macbook to give me some Apple keyboard specific actions as I'm used to them on a Mac combined with Ctrl-based actions I'm used to on a PC, but obviously KR4MB doesn't have the ability to program keyboards.
