There is no way that I know of, right now, to get the information
printed inside the argument section of the frame info. However,
what the dbx is doing, I believe, is simply printing the contents
of the %i0-%i5 registers. This trick only works on Sparc.

Based on the description of what you're trying to do, you should be able
to write a small script/program that starts the debugger with your core
file, extracts the backtrace, then selects one frame after the other and
issue a series of print commands. Your script/program would then
post-process the output and stuff the value of the registers where you
want to see them.
