well, since we found out, that it's the kernel's fault... has anyone
already dared to fix it and provide some patch? :-)

after a quick look at arch/mips/kernel/traps.c (2.4.20) it seems that
it's just a matter of adding a few addition switch-cases to do_cpu(): ?

        switch (mips_cpu.cputype) {
        case CPU_TX3927:
        case CPU_TX39XX:

...and close this bug; if provided with a new kernel image I would be
quite happy to test it, as building on a r3000a @ 20mhz with low memory
isn't quite fun...
