Bug#596598: xorg: (Intel 82852/855GM) Total machine hang as x starts, leaving blank screen

[Chris Bell <chrisbell@3966.ukfsn.org>]

Package: xorg
Version: 1:7.5+6
Severity: important

This machine is normally updated frequently using aptitude. Machine has often hung after a regular kernel upgrade, but the usual temporary cure using a previous kernel did not work this time so I did a total re-installation. Still suffers a total hang leaving a blank screen, and requires a power cycle. Used i386 squeeze businesscard downloaded today, 2010 09 12.
HP Pavillion dv1000, 1GB RAM, Intel 82852/855GM/855GME chipset with IPW2200-BSS.FW, fault occurs both before and after wireless firmware added using single user recovery mode.
I did a total machine backup using Knoppix before re-installing, so all logs are available, although I could not find any relevant information.
