The biggest problem with the graphics display is that the BIOS lacks the information that it can display 1400x1050 - only 1280x1024 and 1600x1200 is there. That's the reason the framebuffer can't be run with the native resolution and the BIOS has to be patched with 855resolution before starting X.

I contacted Acer on 2004-11-20, complaining about that problem and asking them to provide a fully functional BIOS. Two weeks later the answer is there; Acer refuses to provide a new BIOS because the pre-installed operating system (Windows) works ok with it. That's all, they won't support non-ms people.
