Ohh, absolutely. This statement tests for a bug in XFree86 loader system
that prevented it from loading sub modules after a certain stage in
initialization. This was fixed before 4.4.0, but remained just in case
things break again.
However, I don't understand why this would not resolve - the code to load
i2c module (as well as resolve the symbols from it) is just preceding this
line - if this line breaks so would most of other code.
Or, are you saying it is the data-like access that is at fault ?
