I'll contact him.

Well, I think we could use a few tricks to allow this.
After all, the stub is in control of the information
sent to GDB. We can translate segmented addresses
into linear addresses for GDB, for instance. However,
I do believe GDB doesn't support 16-bit code, but I'm
not sure. Oh well, we'll figure something out...
At last resort we could hack GDB ;)
