Another approach is to simply write out the .pat file, after doing "addxy", 
and manually process the fields into grass att and cats files, after running 
v.in.arc only for the linework.  Then support the updated vector coverage.

to manually process the fields to dig_att it do this:
awk '{printf "A %14.6f %14.6f %8d\n", $2, $3, $1}' arcpatfile > $LOCATION/dig_att/newcov

where $1 is the -id and $2 and $3 are the added xy.

i saw a demo doing this with i.ortho or something like that, but i
couldn't begin to explain it more..
