Unfortunately, the hardware doesn't support NPOT textures.

Native resolution of 1024x768x16 requires 4.5 MB of video ram, including z-buffer. Would it be possible to offload any of the buffers (i.e. back-buffer or z-buffer) to system ram? If necessary, i could dig some more into the drivers code...

This is one of those things that could be solved with the new memory
manager.  You could either allocate per drawable back/depth buffers or
potentially but the buffers in AGP memory.  Some just needs to do the
work.
