Intel has (had?) an EFI implementation for IA-32 machines.  You put
that on a floppy disk, boot the system with it, and you get an EFI
prompt (nshell prompt, to be exact).  From there you can launch your
own EFI programs.  The GNU EFI support has support for building IA-32
EFI applications, but it hasn't been tested in a while (not since I
got IA-64 hw to play with, to be exact).  However, provided you have a
toolchain that builds valid IA-64 EFI applications, I think it's very
likely that the IA-32 side will also work, so it may be worth a try.

Hope this helps,
