It does. However the AMD K5 Model 0 has two flags swapped and I think (from memory) that they are APIC and PGE (9 and 13). The next "Cyrix" patch will swap them back (as long as you read x86_flags and don't do your own CPUID). I have no idea of global pages actually work on the model 0 K5 though... :-)
