OK, so I got back on the machine and I do have it in make.conf here: mark@c2RAID6 ~ $ cat /etc/portage/make.conf | grep CPU_FLAGS #CPU_FLAGS_X86="mmx sse sse2 ssse3" CPU_FLAGS_X86="aes mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3" mark@c2RAID6 ~ $ and I guess like you I do not see it in /proc/cpuinfo: flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 popcnt aes lahf_lm ida arat epb dtherm tpr_shadow vnmi flexpriority ept vpid It appears more study is needed.
