It appears to already be a package, although not up to date.  There is a
bochs-2000_0325a version which is under the LGPL.

Bochs has a debugger.  I haven't tried it and don't know what it is good for.
There is always printf.  You might have to add emulation for your card.

Freedos is open source.  There might be a way to add instrumentation.
