In all of Adobe's font dictionaries, there exists another dictionary
named FontInfo.  Within FontInfo there are two numbers:
UnderlinePosition and UnderlineThickness.  They are both in the
Character Coordinate System (to use them, divide by 1000 and multiply
by the current point size).  For example, the numbers for Courier are
-82 and 40, so in 12 point, move -.98 points (-82/1000*12) from the
baseline and stroke a line .48 points (40/1000*12) thick.  You can use
the stringwidth operator to get the proper length.

For a more detailed explanation, look in section 5.3 of the red bood,
"Font Dictionaries".  I'd write a procedure for you, but my
PostScript, as of late, is a bit rusty :-(

In a bind, just use italics :-)
