I've included it as an attachment (very small -- only 14k).
I forgot to add in the readme file you need to create the test device:
cd /dev
mknod test0 c 252 0
Once you get it running, you can enable the output of the newbus debug code
by editing mod/test_bus.c and setting DEBUG to 1. You'll have to re-install
testmod before your changes will take effect (the testmod program loads
testmod.ko from /modules).
