Looks like necessity is the mother of invention. Solved this problem with a 
shiny new module d.bearing:

The new module solves the problem I had (plot a transect from x,y along 
bearing theta, to given radius) and will optionally save the result as a new 
vector.

if anyone is interested i will post the source it for general consumption.

Here is the manpage from my local sources:
