  According to /proc/cpuinfo, it does have mmx
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx
constant_tsc arch_perfmon pebs bts aperfmperf pni dtes64 monitor ds_cpl
vmx est tm2 ssse3 xtpr pdcm movbe lahf_lm dtherm tpr_shadow vnmi
flexpriority

  And while we're at it...
