Ideally you need to read the codes to be sure, but the speedo is driven from the front left ABS sensor, so I'd be looking at that first.
Some people are like Slinkies, they serve no useful purpose but they still bring a smile to your face when you push them downstairs.

I would still suspect the ABS module, as Luxobarge says, speedo signal is from n/s/f wheel sensor.
When you say you've done the usual abs unit change, have you had the joints resoldered or just replaced the unit?
Not sure if your model is OBD11 compliant, may need to make a flash code reader to check for any codes.
