Yes, I did it.  I had to try several permutations to get it to work, but
the one that did was having the "iffparse.library" loaded in memory, having
the "iffparse.dbg" file on the current directory and having the sources
located in a subdirectory of the current directory.  I used the -sPATH
option on SDB to make the source subdirectory available, and did 
"ll iffparse" in SDB.  Other combinations of names didn't work.

Once the .dbg was loaded, SDB would switch back and forth between symbol
tables with "ax".  Worked well.  I haven't tried it with a device
driver, so I can't say how that works.
