    Oh how I loved (as in loved to hate) the near and far pointer rubbish :P
    And EMS was truly awful! You had to raise an interrupt saying you want this 64k block allocated in this highmem block...

    the Flat 32-bit model was just so much easier to work with!

    But seriously x32 is what ia32 _SHOULD_ have been. 8 registers where 2 of them are "special purpose' -> so only 6 registers...

      You're right, ESP and EBP are anything but 'general purpose', meanwhile those extra 8 registers we get in x86_64/x32 all are. The x86 architecture is indeed really register starved.

        omg, someone mentioned main mem and EMS. I had just sealed these old wounds.
        EMS was so horrible. Some progs needed it, some hated it so you always had to reboot when you wanted to use a different program.

        on topic:
        Gentoo rocks.

          Hm, how did I build 32bit mesa (and supporting libs/software) then?

            Manually or through third-party tools/repos. But you already knew the answer to that, so why did you ask the question to begin with?

              Gentoo is one of the first Linux distributions to release a packaged installation for the Linux x32 architecture...

              Mozilla should obtain x32 from Gentoo soon. Gentoo's x32 development lead to a patch that is being pushed upstream, as does many of the other things Gentoo does:
