New installation of ubuntu 15.10 tried. Previously was using ubuntu 11.04 with intel i915 linux drivers.
Installed latest intel drivers using :
intel-linux-graphics-installer_1.2.1-0intel2_i386.deb and 
Graphics (Unity Windows Manager) still operational - but is slow. Compiz normally taking 50% of cpu time.

There were improvements pushed in kernel and Mesa that will benefit to your system, so please re-test with latest kernel & Mesa to see if this issue is still occurring (including new installer in https://01.org/linuxgraphics/downloads)

Kernel: 4.2.0-16-generic
Platform: 82845G/GL[Brookdale-G]/GE - (pci id: 0x2562)
Mesa: 10.6.0 [Please confirm your mesa version]

In the meantime, assigning to Mesa product (please let me know if I am mistaken with this GPU Hang).
