[gentoo-user] Aluminum iMac framebuffer?

[Simon Hunt]

I can't get a 1680x1050 framebuffer (my native resolution) or any widescreen
framebuffer on this intel iMac and the console looks pretty bad because of
it. The best I can use is 1024x768. I have a Radeon HD 2400 XT video card.
The Radeon framebuffer "radeonfb" in the kernel doesn't support this card.
What can I do?
