This is what I recall (I think it's a (fairly) complete list):
(note that the RCS DRI sources are not completely nessecary, as it is just
more-recent code)
** compile & install instructions for G400 dri **
* You need: FreeBSD 4.1 & XFree4.0.1 sources (I guess 4.0.0 will do just fine,
but haven't had experience with that)
* When having compiled & installed XFree, move to
xc/programs/Xserver/hw/xfree86/os-support/bsd/drm/kernel, where
`Makefile.bsd' can be found. The SUBDIR line in this file specifies in which
subdirectories sources should be built. XFree's standard is:
SUBDIR = drm tdfx gamma
Now, we want G400 accel, not whatever tdfx might be! So change it to:
SUBDIR = drm mga gamma
'Kay. Not quite ready yet. Upon compilation, some files in the mga
subdir (i.e. mga/mga_dma.c ) will not compile. This is due to some version
checks in drmP.h which are not properly set (haven't submitted a bug
to the dri team yet though). The following patch will correct it (just
search through the drmP.h file and erase any version number checks for
versions bigger than 500005):
-- patch drmP.h
52c52,54
< #if __FreeBSD_version >= 500005
---
> /* #if __FreeBSD_version >= 500005
> #include <sys/taskqueue.h>
> #endif */
54d55
< #endif
56c57,59
< #if __FreeBSD_version >= 500006
---
> /* #if __FreeBSD_version >= 500006
> #define DRM_AGP
> #endif */
58d60
< #endif
520c522,524
< #if __FreeBSD_version >= 500005
---
> /* #if __FreeBSD_version >= 500005
> struct task task;
> #endif */
522d525
< #endif
-- end patch
Now everything should compile nicely.
* Copy the kernel modules to /modules (these are: mga/mga.ko ; drm/drm.ko
and gamma/gamma.ko although I don't know if gamma.ko is needed)
* Edit /boot/loader.rc and add the lines:
load agp
load mga
So that upon reboot, the new kernel modules are automatically loaded
* Edit your /etc/X11/XF86Config:
In the section "Module" add (if not already):
Load "glx"
Load "dri"
And create a new section outside the "Module" section:
Section "DRI"
Mode 0666
EndSection
But be advised that this will allow all users on the system to use dri.
See the XFree docs for more info on changing the XF86Config file.
* reboot, and you'll find some extra lines in your dmesg:
Preloaded elf module "agp.ko" at 0xc03390ec.
Preloaded elf module "mga.ko" at 0xc0339188.
Preloaded elf module "drm.ko" at 0xc0339224.
(drm is automatically loaded)
drm0: <Matrox MGA G400 AGP graphics accelerator> mem 0xe2000000-0xe27fffff,0xe2800000-0xe2803fff,0xe6000000-0xe7ffffff irq 11 at device 0.0 on pci1

Note that the `pciX: <Matrox MGA G400 blablalballa>' should have changed
to `drmX: blalblblablalb'..
When starting X, `/var/log/XFree86.0.log' should display some lines about
drm:

* READY!
* Debugging: haven't had that much trouble actually, but I forgot to check
that some board in my PC had the same IRQ as my G400.. My NCR SCSI
card also used irq11 and caused things to refuse working.
Hope this is any help. Quite some credit should go to joeo@cracktown.com
for this info..
