But seriously, isn't using minor loop synthesis (Bill Sloman, where are
you?) and using the drive in it's intended application as a speed servo
a suitable way as well?

Beats me. This is a pretty impressive thread about a rather nasty
problem. My guess would be that the dead time in the PWM drive is the
source of the problem, but I've not worked on comparabe hardware, and
consequently my intuitions aren't worth much.
