This is my dmesg:

Hope I didn't cut the most interesting part.

That's done. Hmmm ... I didn't see it commented.

While looking at dmesg above, grf_cc.c should be the right one.

However while changing grf_cc.c ...

----- cut here -----
    if (viewioctl (0, VIOCGSIZE, (caddr_t)&vs, -1, NULL)) {
        /* XXX type of vs ? */
        /* fill in some default values... XXX */
        vs.width = 640;
        vs.height = 400;
        vs.depth = 2;
    }
----- cut here -----

... into ...

----- cut here -----
    if (viewioctl (0, VIOCGSIZE, (caddr_t)&vs, -1, NULL)) {
        /* XXX type of vs ? */
        /* fill in some default values... XXX */
        vs.width = 1024;
        vs.height = 768;
        vs.depth = 16;
    }
----- cut here -----

... didn't change anything!
