no - i did not patch anything - the new version is "supposed to work" - i will check through my installed zaptel/oslec versions to see what might be missing.
another "question" is I thought you already closed Hyperthread in Bios, otherwise the system should show 2 cpus, but now only 1 is visible, (run cat /proc/interrupts)
and also the system said your cpu is a P4, not mentioned hyperthread, it looks a little strange. could you check?
