Yep, that's my fault.
I'll post a fix to Matthew's platform drivers list asap.
For now just ignore it. The warning is a false positive one and
is harmless.
Thanks for bringing this up!

Interesting io port 0x930..., definitely not default.
You might want to double check with a fixed kernel if it
is registered correctly in /proc/ioports and the WARNING
vanishes. But no need to explicitly check, just have a look
when you try a newer one anyway. Thanks.
