v.in.ascii

You will have to transform your data (e.g. with awk) to fit the standard 
format. Something like this (untested) should work:

awk -F"," 'BEGIN{i=0} {i++;print "L 2 1";print $1,$2,i;i++;print 
$3,$4,i;print "1"}' YourFile | v.in.ascii -n format=standard 
out=YourMapName fs=" "

See the v.in.ascii man page for details.
