do you have x86-64 support enabled in these binutils? This breaks
relocations 32->16bit.

src/cpu/i386/reset16.inc is the culprit. See the freebios2 tree
for a wild but working implementation of reset16.inc. The 
"jmp _start" is there implemented as:
reset_vector:
        /* jmp _start */
        .byte  0xe9
        .int   _start - ( . + 2 )

This should also be changed in the old LinuxBIOS tree. It works fine.
