In my quest to convert a module from 2.2 to 2.4, I came across
a nice oops (it actually was from their code that I thought I didn't
have to touch...).
The oops comes when trying to access address 0xd2000, which the
code for this robot controller has hardcoded as its "BASE_ADDR"
Were the base addresses for io cards moved between 2.2 and 2.4?
