I'm not using mga_dri.o (since it doesn't compile on 2.2 kernels)
but for the other two I'm doing the same as you.

Why not let the driver load the hal itself ?
I don't have that line in my config.
In my log note that mga_hal_drv.o is a SUBmodule:
% grep -i5 mga_hal /var/log/XFree86.0.log
(II) Loading /usr/X11R6-v4/lib/modules/libvgahw.a
(II) Module vgahw: vendor="The XFree86 Project"
compiled for 4.2.99.4, module version = 0.1.0
ABI class: XFree86 Video Driver, version 0.6
(--) MGA(0): Chipset: "mgag550"
(II) Loading sub module "mga_hal"
(II) LoadModule: "mga_hal"
(II) Loading /usr/X11R6-v4/lib/modules/drivers/mga_hal_drv.o
(II) Module mga_hal: vendor="The XFree86 Project"
compiled for 4.2.0, module version = 1.0.0
ABI class: XFree86 Video Driver, version 0.5
(==) MGA(0): Matrox HAL module used
(**) MGA(0): Depth 24, (--) framebuffer bpp 32
(==) MGA(0): RGB weight 888
I think that the module is failing to load the hal because it is already
there, and giving up (that could be a real bug).

I also note that you have a dual head config, but both heads
have the same PCI ID. If it is a dualhead card, you need lines
Screen 0
and
Screen 1
in the Device sections.
