The VM network today only runs DOCSIS1 or EuroDOCSIS. There is no DOCSIS1.1 or DOCSIS2 on the VM network to the best of my knowledge.
Moving onto the speed issue, have a look at this news item from VM:
http://www.virginmedia.com/customers...atus/ambit.php
It states:

After further investigations we have now concluded that there may be circumstances where Ambit 100 and Ambit 120 modems do not meet the performance criteria for the Broadband Size XL service.
We recommend that any customers who have either of these modems now request a cable modem swap-out in order to get the maximum performance from their broadband connection.
The Ambit 200 modems meet the specified performance criteria.

The Ambit 200 may indeed be DOCSIS2 capable but as the underlying network doesn't run DOCSIS2 today it doesn't make any odds. It just happens to be a newer, more capable modem. Also the maximum downstream speed of both DOCSIS1 and DOCSIS2 is 38Mbps under perfect conditions after removing the DOCSIS overhead.
If you're trying to run 20Mb you'll be better off with an Ambit 200, 255 or 256. For a while there was a method for getting a self install swap out through the website because that's what I did. I can't find it now though.
