[i855] dual-head configs are ill

Bug Description

Using a config that worked in hoary, I try to run with a external monitor hooked
up to my laptop (a Dell Inspiron 700m). This causes xorg to crash with the
primary error being:

(EE) I810(0): vm86() syscall generated signal 11.

After this crash, if I replace the xorg.conf with one that works for single
display (on the laptop LCD) and restart X, X will not start. Only after the
machine has been rebooted will the X server start again. My video hardware:

0000:00:02.1 Display controller: Intel Corp. 82852/855GM Integrated Graphics
Device (rev 02)

I will attach the xorg.conf that produces the problem, as well as the Xorg.0.log.

Also, this issue seems very similar to a bug filed at freedesktop.org, however,
the signals generated are different:

I have the same problem on my Toshiba Satellite A50. Just the signal number is 4.
Would be a temporal solution for me to compile the xorg with gcc-3.3?

you can try gcc3 if you want, but it didn't seem to help any here

I have to correct myself: my case was the latter one case mentioned in the issue
and not this one which appears actually sooner.

This patch -- https://bugs.freedesktop.org/attachment.cgi?id=4323
fixes my problem when applied to the version of i810 in dapper: xserver-xorg-driver-i810-1.4.1.3. I think you might consider applying it to the official package in dapper.
