I will be able to address d.legend issues when I get back to work next
week. The logic of the module is a bit of a nightmare so I like to do
it personally.

but quickly,
- Labels for smooth legends (incl FP maps) worked once upon a time.
  see r.category
- There are options for range= and labels= so you can make the breaks
wherever you want them with a small bit of math. see also use=
ps.map's automatic legend ticks may be prefered but offer much less
control.
