b) agp / agp_amd64

Hardware involved:
ASRock ALiveDUAL-eSATA2
"Northbridge": NVIDIA ( former ULi / ALi ) M1695
Southbridge: NVIDIA nForce3 250 <-- incl. AGPA
AMD 64 Phenom
Matrox G550 AGP
#########################################################################
Procedure to reproduce:
1.) Clean fresh install from CD-ROM 1,
select "All" ==> including X11
2.) install xf86-video-mga ( sysconfig / ftp )
3.) add drm and mga to /boot/loader.conf
4.) create /etc/xorg.conf via "X -configure"
#########################################################################
Observations, as far as I can interpret:
(A) from dmesg:
(1) "Northbridge" --> PCI-express seems to be recognized correctly.
(2) agp_amd64 correctly identifies the G550 with chip 2527 from vendor
102b,
but on pcib0 !?! <== !!!
(3) agp fails to finish loading
(4) Southbridge gets recognized on pcib1
(5) Matrox gets recognized on pci slot pci4 on pcib1
(6) vga driver detects Matrox as vgapci0 in pci4
(7) drm binds to this vgapci,
(8) but cannot initialize this vga device as AGP
(9) consequently, the system continues with VGA as minimal working
configuratgion.
(B) from /var/log/Xorg.0.log:
Starting X, the consecutive errors are as expected:
(10) The modules dri and mga get initially loaded
(11) The mgag550 can be contacted, but not successfully initialized
(12) In consequence, initializing drm fails.
(13) In consequence, initializing dri fails.
My subjective guess / impression :
This may have to do with agp / agp_amd64
being called on the PCI-e,
but not on the AGP bridge.
If additional special information is needed,
reply your request via above private e-mail address
(I'm not on any FreeBSD mailing lists yet),
and I'll try to provide it.
Looking forward to your answers.
Kind regards!
P.S.: Yes, I have searched ... and ... and ...
Closest I could discover:
There were some hints to vga and agp mis-interfering ~ 2 years ago,
but that has been sorted out and doesn't seem to apply to this problem ...
