I built a kernel with these option enabled and attempted to load the module. That failed with the same message as you saw. Looking at my dmesg this is related to an unknown module option:
This option is specified in /etc/modprobe.d/toshiba_acpi.modprobe, commenting out that option allowed the module to at least probe for toshiba hardware. As I don't have a toshiba to hand I cannot test it further. Could you retest the kernel you built with that option commented out and let us know here whether it works for you.
