This is a long shot.

Between me and geri pircher we are trying to get the agpgart driver working for the pegasos 1 and amigaone boards (using the ArticiaS northbridge http://www.mai.com).

Find the attached source file (articias-agp.c), You might need to remove the debug code.

So far, the aperture size works and is detected as 204m, but the gatt table cannot allocate any  memory - complains that ioremap is using memory from RAM.

The ArticiaS masks its bridge memory (i'm sure the uninorth does the same?).

Is there anyway to find out the mask memory, or is the code completly wrong?

This source code should work on 2.6 kernel.

Thanks for any help or guidence in advance.
