In real mode, GPF's happen if, and here's a cut and past from Ralph
Brown's interrupt list:
Notes:  called in real mode when
            an instruction accesses a memory operand extending beyond
offset
              FFFFh (i.e. WORD at FFFFh or DWORD at FFFDh or higher) in
segment
              CS, DS, ES, FG, or GS
            a PUSH MEM or POP MEM instruction contains an invalid bit
encoding
              in the second byte
            an instruction exceeds the maximum length allowed (10 bytes
for
              80286, 15 bytes for 80386/80486)
            an instruction wraps from offset FFFFh to offset 0000h

So I just want to be able to intercept the interrupt and use my own
exception handler.
