Hi,
I am (currently) working on a Compaq dc7600. Knoppix 5.0.0 works perfectly fine - I am posting this from it. I downloaded and burned 5.0.1 and it fails to boot - this specific copy works perfectly fine on several other machines. Booting with no cheatcodes, simply freezes a blank (except for a single dot in the middle) display. Booting with failsafe, freezes when it gets to the PCI configuration.
Here is output of 'sudo lspci -v', as the name of the forum states, from 5.0.0:

Not sure how to read this myself, I am just hoping that this can be of use to somebody working on the next version.
