at first sight, this is not this block which trigger the fault, but
the test following:

    455                 if (KERNELMODE(vframe->tf_cs, vframe->tf_eflags))
    456                         goto we_re_toast;

not sure at all what this means, I'll try to dig a bit more. I can
provide anything but a crash dump, I can easily reproduce this bug.
