Well, qemu seems confused (as usual).  Having "lm" and "lahf_lm"in the CPUID
feature flags and a 48-bit virtual address space implies being 64-bit, but
Intel Family 6 Model 13 implies being the 32-bit only Pentium-M.

Since real HW doesn't get this confused I'd classify it as a qemu bug.  (We've
seen several similar "impossible" cases in LKML.)
