The presence of vdg windows has no connection with whether you use a 6809 or 
6309. There is also no correlation with which version of NitrOS-9 6809 or 6309 
you are using.

There should be only one reason why V1 and V2 are not loaded in 6309 NitrOS-9 
but are loaded in 6809 NitrOS-9, your modules must have bad CRCs. There is no 
way that we can tell you what is wrong unless you post a list of the contents of 
you OS9Boot file.
It is also not clear if you have a problem with your build from the Mercurial 
source code. That issue can be eliminated if you try booting from a 6309 nightly 
build of NitrOS-9 rather than your own.

If you want vdg windows to work, your OS9Boot file must contain either CoVDG 
small or CoVDG full in addition to V1 and V2. As you mentioned, V1 and V2 are 
not required as any of the W windows can be converted for vdg use.
