OK as in "it works for me", and OK as in "this is the correct usage" are two different things. I believe that for a 64-bit kernel either -mabi=64 or -mabi=n32 (-mlong64) are the right long term answer, part of Daniel's problem was that his bootloader couldn't deal with ELF64. -eric -- Eric Christopher <echristo@redhat.com>
