vgsp: m98 - dump the program prologue (entry offset) and the param/const-0 page at launch

m97 settled the fetch question: zeros planted at the QMD's program offset
executed and trapped ILLEGAL_INSTR_ENCODING (0x9) at PC=0x109800 - the SM
instruction fetch and const reads through our shadows work; the m90-m96
MMU_NACK at PC=0x109880 is a memory access by the prologue instruction at
+0x80, almost certainly the first global load using a guest-VA device
pointer from the param buffer (c[0x0]). Dump the program page from the
entry offset (40 words) and the param page (16 words) so the access
instruction and its pointer arguments are visible in the log.
