Sure. (Prior to recent pre kernels, use the message "lost interrupt" instead of
"timeout waiting for DMA")

The harddrive LED is now stuck on and the machine is forever hung, I must turn the
power off and back on before anything works.

I previously reported this under 'use DMA by default' which turned out to actually be
wrong. The PIIXn tuning option is available only when the DMA/default option is
enabled.
Turning on PIIXn tuning causes the system to hang at the above.
The .config file is located at http://stuph.org/config-2.3.99-pre9-2.PIIX
The lspci output is located at http://stuph.org/lspci-2.3.99-pre9-2
Any more questions, feel free to ask.
