Yes, that's what I mean. If I ctrl-alt-+ to 640x480, for example, I get
normal 1024x768 resolution, but only see a 640x480 window, and a few ugly
copies of it in the other 'quarters'.

I'm assuming this would have the same issue, but I haven't really
experimented, since I'm not sure of the numbers on ppc. I still have to try
vga=ask or something...
