Mark i2o config broken on 64-bit platforms as it generates these:

which are apparently non-trivial to fix (eg: inserting a cast through unsigned
long is not correct according to Linus). This would be due to struct
sg_simple_element only having a 32-bit addr_bus value.
There are also a number of "TODO 64bit fix" comments.

NAK - it appears to be broken for 64bit user space only
Agreed.
That was the conclusion when I joined the cast of thousands who tried to
kill this warning, and found that out...
