This gives me hdmi, dvi and vga, where I can use VGA as one screen and either HDMI or DVI as the other. Mine's a powercolor Go! brand, but it doesn't matter...should be around $30-40 USD. Do not enable KMS, and all is well. It does take a while to switch back to syscons, especially if you are using a high resolution mode. I can't wait to use newer cards when ttm is possible, but performance is not lacking with OSS drivers on the 4xxx radeons. Matt
