I think that debug.c won't compile now, it was created when only VT was 
supported. However you can take the relevant show_code function and add it to 
vmx.c (Intel) or svm.c (AMD). Call it at the end of handle_exception()
Function.

Anyway since the problem is the partial implementation of real mode emulation, 
thus a single instruction won't help much.
