    Ok, this is due to the silly library stub seemingly thinking that a large
    positive value is in fact a error condition due to sign problems.

    That doesn't mean that the kernel is broken: there are other system calls
    that return large numbers that might be thought of as negative even though
    they aren't errors (just an example: mmap() can return addresses with the
    high bit set, and always could).

    Instead of testing the sign bit, the low-level system call should
    probably do something like this:

    ... do system call, return in %eax ...
    movl %eax,%edx
    addl $4095,%edx
    jc error error if return was -1 .. -4095

    Is somebody willing to fix up the module loader?
