Description
I am not really sure this is really possible, but here is the scenario:
My machine has 2 unsupported ATI Radeon HD 3780 video cards. Each card has 512 Mb of video memory. My machine also has 4 Gb of memory but because the video memory in both cards are mapped to the memory address space, Haiku only reports 3072 Mb of memory installed.
I do understand that even running in VESA mode, the 512 Mb of the primary video card would be mapped to the memory address space too (so would "eat" 512 Mb of it), but the second video card is completely unused and an option to completely disable it would be mostly welcome so I could reclaim those 512 Mb of unused memory.
of course, the other option is switching to 64 bits. :)

Well, it seems like 'far, far away..' was 7 months.
Closing as non-IGP Radeon HD 3780 cards should be working. Feel free to open a new issue if you still have problems :)
I am moving this to the radeon_hd component, this may be a feature of the radeon_hd driver some day far, far away.. you would have to definitely work through the ATI AtomBIOS to do this.
