[vbox-dev] MacOs Native Fullscreen

Hey guys,
I'm working on Mac OS native fullscreen support for VirtualBox.
It's my first time hacking the source, so I'll need some help. Ok?

I've already found the class where you call showFullscreen() and modified the UIMachineWindow to show the arrow on the right corner of the title bar.
The code is self contained so I don't think we're going to have compatibility issues, even with older versions of MacOs, like 10.6.

One minor caveat is that you'll need MacOS SDK 10.7 to compile the source. I don't think it's a problem since you'll still be able to target older versions, like 10.6.

What I really need to do now is to test the code I've written in a proper way but I can't manage to turn my Virtual Machines on.
I ran the loadall.sh script, so I don't think it's a kernel module problem.

Could you give me some directions on what to do? The error I receive is:
Failed to load VMMR0.r0 (VERR_GENERAL_FAILURE)

And the details say:
Result Code: 
NS_ERROR_FAILURE (0x80004005)
IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}

In debug mode, this is the stacktrace:
