    Hello,

    SSE and SSE2 instruction set support

    Glad to see this, unfortunately when I cat /proc/cpuinfo I don't see reference to sse or sse2 that I ordinarily see on a 386 box in flags:

    I am running LX86 on a power5 570. Does this make a difference?

    • I have verified that, on a RHEL 5 U4 installation of a Power6 machine, the cpuinfo looks like:

    • On a Power5 partition, same OS:
