Looks as if I'll need to reboot to find that out; in the mean time:

While I'm waiting for the fsck to complete, I'll remind folks that this
hardware & configuration (as it was, with DRI enabled) was working fine
in stable/6. In stable/7, it works if I disable DRI. When I was using
X.org built under stable/6, I also needed to disable DRI to run X.org
under stable/7 (or /8) reliably (using the compat6x port).
The hardware in question is by no means "cutting edge" -- it has been
around for years.
OK; here's the stanza for the ATi device:
vgapci0@pci0:1:0:0: class=3D0x030000 card=3D0x00d51028 chip=3D0x4c66100=
2 rev=3D0x01 hdr=3D0x00
vendor =3D 'ATI Technologies Inc. / Advanced Micro Devices, Inc.'
device =3D 'Radeon Mobility 9000 series (ATI MOBILITY RADEON 9000 (=
Microsoft Corporation -)'
class =3D display
subclass =3D VGA
bar [10] =3D type Prefetchable Memory, range 32, base 0xe0000000, siz=
e 134217728, enabled
bar [14] =3D type I/O Port, range 32, base 0xc000, size 256, enabled
bar [18] =3D type Memory, range 32, base 0xfcff0000, size 65536, enab=
led
cap 02[58] =3D AGP 4x 2x 1x SBA disabled
cap 01[50] =3D powerspec 2 supports D0 D1 D2 D3 current D0
(obtained after booting with the /etc/ttys entry for xdm turned off).
Let's see... dmesg says that the Ati card is at irq=A011; vmstat -i
only shows "cbb0 cbb1++*" for irq 11. I *think* dmesg is showing
that nearly everything on the machine that isn't explicitly listed
in the "vmstat -i" output is assigned to irq 11; I've attached a
copy of dmesg.boot.
I'll try setting AGPMode to a non-default value & see what happens.
Thanks.
Peace,
david
