I am doing that now. I just haven't committed that part yet. BTW, I
don't think the current compute_allocate_resource can handle the
legacy vga mem resource (0xA0000-0xBFFFF) by modifying the
read_resource() of either the VGA device or K8 NB. I always got
strange allocation (like resources allocated near 1MB for other
devices). I guess the current K8/northbridge.c is the best thing
I can get.
