    After a quick check of the intel pentium spec, I didn't see any way to expressly disable the TLB and only the TLB. It can be flushed and invalidated using the INVLPG instruction, but of course the second after you flush it, it'll fill back up again with fresh entries.

    If there was such a bit to enable/disable it, (and there probably is) it would probably be controlled by a bit in one of the MSR registers which are mostly undocumented/confidential.
