I have currently installed on my ze4610us Knoppix 3.4. I encountered the same problem. Now I use the 2.6 kernel and this is the boot prompt cheatcodes i used to get this to run.

knoppix26 apm=off nolapic noscsi momce acpi=on

The nolapic is needed so acpi will work. What's happening o theboot that hangs is that it is looking for a scsi device that is obviously not there. BTW this only startedhappening on this laptop with knoppix 3.4, Knoppix 3.3 did not have this happen. And yes it still happens with 3.6 BTW

Hope this helps.
