I'm running FreeBSD 5.2.1-RELEASE on an E-machines M3505 laptop.
I've was hoping to get DRI working under X11. Alas, I am thwarted.
The video card is an ATI Radeon Mobility U1.
drm0@pci1:5:0: class=0x030000 card=0x2029161f chip=0x43361002 rev=0x00 hdr=0x00
vendor = 'ATI Technologies'
device = 'Radeon Mobility U1'
class = display
subclass = VGA
It was straightforward to patch sys/dev/drm/radeon.h to allow this
card to probe (gotta file a PR soonish):
{0x1002, 0x4C57, 0, "ATI Radeon LW Mobility 7500 M7"}, \
+ {0x1002, 0x4336, 0, "ATI Radeon Mobility U1"}, \
{0x1002, 0x4C58, 0, "ATI Radeon LX RV200 Mobility FireGL 7800 M7"}, \
# dmesg | grep drm
drm0: <ATI Radeon Mobility U1> port 0x9000-0x90ff mem 0xf0100000-0xf010ffff,0xf8000000-0xfbffffff irq 10 at device 5.0 on pci1
info: [drm] Initialized radeon 1.10.0 20020828 on minor 0
But, X11R6 4.4.0 doesn't want to play, I get:
"XFree86-DRI" missing on display ":0.0"
I've followed the advice on the DRI troubleshooting webpage:
<http://dri.sourceforge.net/cgi-bin/moin.cgi/DriTroubleshooting>;
I infer the core issue is this laptop's AGP chipset isn't supported,
acording to agp(4):
pcib1@pci0:1:0: class=0x060400 card=0x00000000 chip=0x700f1002 rev=0x01 hdr=0x01
vendor = 'ATI Technologies'
device = 'A3/U1 PCI to AGP Bridge'
class = bridge
subclass = PCI-PCI
It looks like FreeBSD-current has an easy-to-extend AGP structure
in sys/pci/. But, other than introducing device probes, I have no
grasp how to pull in anything like support.
Any pointers? I _think_ the Mobility U1 is also known as a 'IGP320M'
Northbridge chipset:

(I'm grasping at straws here...)
Thanks for any advice.
