x86info does report sep, but arch/i386/kernel/cpu/intel.c has this to say:
/* SEP CPUID bug: Pentium Pro reports SEP but doesn't have it
until model 3 mask 3 */
if ((c->x86<<8 | c->x86_model<<4 | c->x86_mask) < 0x633)
clear_bit(X86_FEATURE_SEP, c->x86_capability);
whereas our cpu is
cpu family : 6
model : 2
so, no SEP for you. I imagine we can bump the model and mask to 3.
