Ive done a google and the history seems rather curious. Theres too much myth and unsubstantiated facts around this atm. I find information, then I find other information that contradicts that. It would appear that at one time Netgear released one of the DGND3700s (most likely v1) with a vdsl2 modem, but they later withdrew support.
The custom firmware available for the
DGND3700v1 is based on the vdsl drivers which were later withdrawn by netgear. I cant find any reason why Netgear withdrew the vdsl functionality, but because the custom f/w appears to be based on the later withdrawn f/w, then I'm removing v1 from the list. Users can try this at their own risk and the custom f/w can be found at richuds site

here.
It would appear that one of our members
bilbokitz is successfully using a DGND3700 with vdsl, but its unclear which version.
Facts surrounding v2 seem very contradictory, and there may be confusion between this and v1 and its chipset support.. so Im also withdrawing that from the main list until there is official confirmation from netgear or another trusted source.

ETA
I just noticed that golden fibre has also changed his facts re the v2 -
link. This is way too confusing. In future I think its best to leave the list purely for those modem/routers which are advertised & sold by the manufacturer as being vdsl compatible.
