Do ibook kernels support scaling of other resolutions to a laptop's native res? I understand the rage mobility can do this with little or no (in later revisions?) performance loss, and it would solve some issues nicely, such as mol support, hard-coded games, etc.
Try Ctrl Alt +/- which will switch to lower resolutions if your XF86Config-4 is set up for this. Here I have
Modes "1024x768" "800x600" "640x480" Which all work fine.
If you mean if some 300x200 pixel resolution which is below the LCD resolution can be scaled up by X - I don't know that.
On a related note, is there a simple way to make a 1024x768 console display 80x25, such as loading a large font, or something?
Only from my experience from x86, I don't know if this also applies to PPC: The parameter "vga = <number>" ('791' here) enables certain framebuffer modes, I guess google for possible values that use simple VGA.
Or you might indeed try to generate your own font :) -Thomas
