I must say, I am amazed at how quickly responses have come in!
The NorthBridge bug in the VIA chipset does seem to have the register
set to the "faulty" value on my machine. Evidence:

Unfortunately, the patch which was posted at:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0109.1/0817.htm is for
2.4.9:/arch/i386/kernel/pci-pc.c the likes of this file doesn't exist
in 2.2.20... I assume the equivalent is /drivers/pci/pci.c, but it
doesn't have some of the code which the patch plays with,
unfortunately I dont know enough about the kernels to determine how to
"backpatch" this, anyone have a 2.2 patch?!

Woops, now I'm running with 2.7.2.3, doubt that is causing the problem
however, sounds more likely the above issue.
