"intel" driver dies in i830_allocate_2d_memory() with multiple displays on Intel 865G

Can someone tell me what I'm doing wrong, or if I should just file this
as a bug?
Using Debian "unstable" (to have recent versions of X), the 2.6.21
kernel, a "Gigabyte" motherboard with Intel 965G, a card with two TMDS
outputs, and a VGA output on the motherboard. I am trying a three-screen
configuration. Not even two screens works. The driver dies here:
(II) intel(0): Attempting memory allocation with tiled buffers and
large DRI memory manager reservation:
(II) intel(2): Allocating 0 scanlines for pixmap cache
0: /usr/bin/X11/X(xf86SigHandler+0x81) [0x80c8591]
2: /usr/lib/xorg/modules/drivers//intel_drv.so [0xb7c15ec0]
3: /usr/lib/xorg/modules/drivers//intel_drv.so [0xb7c16e6e]
5: /usr/lib/xorg/modules/drivers//intel_drv.so [0xb7c12f2e]
6: /usr/bin/X11/X(AddScreen+0x1ee) [0x80764be]
7: /usr/bin/X11/X(InitOutput+0x21e) [0x80a7b6e]
8: /usr/bin/X11/X(main+0x27b) [0x8076c6b]
9: /lib/i686/cmov/libc.so.6(__libc_start_main+0xdc) [0xb7dc3ebc]
10: /usr/bin/X11/X(FontFileCompleteXLFD+0x1e5) [0x80761a1]
Configuring for one screen works, all three screens display the same
image when I do that.
xorg.conf for the three-display configuration is at
and server log output for that configuration is at
(WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found
This is complaining about the second appearance of the 865G on the PCI bus.
00:02.0 VGA compatible controller: Intel Corporation 82G965
Integrated Graphics Controller (rev 02)
00:02.1 Display controller: Intel Corporation 82G965 Integrated
Graphics Controller (rev 02)
What, if anything, should I configure about that second appearance?
I seem to have trouble associating a TMDS port with a monitor:
(II) intel(0): Output TMDS-1 has no monitor section
I do have three monitor and screen sections, how can I associate one
with the TMDS port? This version of the driver doesn't heed MonitorLayout.
