I think all of these questions about BIOS version, RAM, etc are red
herrings, because the hardware clearly works fine in some (software)
configurations and not in others, which implies the hardware itself is
fine and it's the software to blame.  SO.....

Look for software differences:

* Perhaps try to run the Knoppix Kernel on Ubuntu?  Or at least a
  similar version?

* Try the extra command-line options to the kernel as pointed out

* Check the actual drivers to see if you have the same kernel modules
  installed/running (lsmod).  For example, maybe it's a UHCI v *HCI issue?

* Check your module configuration parameters between the working and
  non-working systems

Good Luck!
