It's a just-in-time binary translator which translates x86
instructions into ia64 instructions. It also does the x86 syscall
emulation all in user-land. With ia32el enabled, the x86 hardware
built into the Itanium and Itanium 2 chips won't be used at all and
due to its built-in optimizer, ia32el may run programs significantly
faster than the hardware translator (though some programs also may run
slower).

CONFIG_IA32_SUPPORT, giving you a significantly smaller kernel and
thereby reducing the number of potential security holes.
