That mmio thing isn't a module but just an option so that is to be expected.
You could try removing the sundance mod withsudo modprobe -r sundance
(If it says it's in use you need to see what it's used by using the
commandlsmod
and then first removing those modules. Repeat until.)
Some modules take parameters when inserted, you can find out those withsudo
modinfo sundance
those are the ones listed after "parm:".
Then you could re-insert it with e.g.sudo modprobe sundance debug=5
I expect that to output to /var/log/syslog or perhaps even to the terminal
you're using to input these commands.
