Quoting Petr Vandrovec (vandrove@vc.cvut.cz):

If you could print return value from register_framebuffer in 
matroxfb_dh_regit in matroxfb_crtc2.c, maybe it could reveal
problem. Maybe that using non-ac kernel fixes problem too.

It never reaches register_framebuffer. It leaves dh_regit at tese
lines:

        else if (ACCESS_FBINFO(video.len) < mem) {
                kfree(d);
                return -ENOMEM;
        }

ACCESS_FBINFO(video.len) is 2097152. Mem is 8388608.

Really... I did not notice in your original email that it
reports G400 as 2MB only device... Can you send me
output of 'lspci -s X:Y.Z -vvvxxx' (where X:Y.Z is
your G400 device, probably 1:00.0 or 2:00.0) with
2.4.19-pre10, and with Alan version? Alan's version
uses data from BIOS to set memory type, and it
apparently made mistake.

In Alan's kernel you should have option to enable procfs
interface - can you enable it and send me also
contents of /proc/driver/mga/fb*/pins. It is binary
file, if you want, you can parse it by matrox_pins
from ftp://platan.vc.cvut.cz/pub/linux/matrox-latest.
