well done geert, :) i am actually working on the beta2 this very moment and will test you new driver tonight :-) i will have to dig into my components box to find a 24c32... (i think i only have 24c04 :)
once we are ready with the new patch, i would like to ask you to write a article on the acme site, on how to use the driver for a few scenarios.
