Actually, we did at one point.  I'm in the process of looking at 
dskprobe.c right now.  I've got a tiny commit that would probably take < 
1.5 minutes to review and merge in my 'memdskprobe' branch on your server.

Other than that trivial piece, I've split the three types of probe, 
0x08, 0x15, 0x41, so each can yield more specific detail relevant to the 
results for the particular sub-function.  No commits for that stuff just 
yet, but perhaps tomorrow.

I also noticed that BX is not being set in the AH == 0x41 probe.  Hmmm...
