Hello.
I have just committed some changes to Kadischi's CVS tree which should rectify the issue with Kadischi built LiveCD media not booting properly on USB CDROM drives.
I am asking that the people who are using Kadischi test the latest CVS tree and verify this works on your USB CDROM drives.
If you encounter early bootstrap propblems and any kernel panics please report the errors if any and send to the list. This fix has been put off for quite some time for the fact I did not have a USB CDROM drive lying around to test with.
It should be all good now, please test it and report your results.
