a while ago i fixed netboot/main.c for PIE/PIC:

      : "0"(*sum), "1"(start), "2"(len)
      : "ax", "cc"
      );

on another note, there's this nxstack patch that looks quite messy but it seems to remove nested functions for good, in that case the ebuild need no longer call    chpax/paxctl (not that if it was needed before, E/EMUTRAMP detection worked fine).
