Now you got me interested. :-)

What kind of a project you're working on, is it related
to Beats of Rage, or something new?

I commited support for that, for *CPU* side:
	http://hg.tuxfamily.org/mercurialroot/hatari/hatari/

With the current *DSP* disassembler, its only possible to have
the disassembly on its own line, but that would look pretty messy,
especially as DSP disassembly includes also address and profiling
information, so I left that out.

I use those "top" count & cycles lists mainly to see where in memory
the hotspots are and how/whether they're close together or spread out.
Then I just start disassembling from somewhere slightly before
the hotspot (to see how code arrives in the hotspot).

I.e. in above case dissassembling forward from the first instruction would
quickly show all the relevant instructions.  I hope doing something like
that is enough for the DSP side...
