This one is the most exciting - finally add support for automagically downloading and pre-pending the VGA VBIOS for the ga-2761gxdk. This should be a framework for future optionroms to be downloaded and used from linxubios.org. I'm not super happy with how congested packages/linuxbios is getting - I think there is definitely some room for consolidation and improvement, but we are hobbled by v2 in many regards. v3 will make this stuff so much better.

[BUILDROM] Download and prepend the VGA VBIOS for the ga-2761gxdk
First try at downloading and prepending the VGA VBIOS for the ga-2761gxdk
board stored on linuxbios.org. This should be generic enough to extend
to other platforms when the time comes.
