Erm, this doesn't look good:

        movl    $GPROC0_SEL*8, %esi             /* GSEL(entry, SEL_KPL) */
        ltr     %si

#define GPROC0_SEL      4       /* Task state process slot zero and up */

Thus, %esi should be 32 == 0x20, not 0x100. :(  I have no clue why that is
screwed up, unless something is overwriting your code segment.  Can you panic
it and do an x/i of sw1b+0x72?  It should look something like this:

 121:   be 20 00 00 00          mov    $0x20,%esi
 126:   0f 00 de                ltr    %si
