Matt: Graphics is ATI Radeon Xpress 200 onboard which uses some 
of the system RAM.  The PC itself is an HP Pavilion t3510.uk desktop 
with an HPvs17x flatscreen monitor and 1GB Ram.

John: The kernel is whatever kernel Lucid installs (I can confirm it, if 
you want but shutting XP & rebooting takes an age)

Matt: Note booting in Recovery mode and with old kernel also fails.
