Fine, but you *should* spec this soon. Because otherwise a developer (as me:))
cannot write drivers, and we need tons of that. On mine part, I'll write the LM for
IOSK developer guide, when I'll start writing floppy driver.
So, I propose you this:

   CKsetIOPerm(baseaddr, length)  // incase of floppy base=0x3f0 length=8, if I
remember well...

tell me how. Write some doc, and all we were happy. I know you don't like writing
docs, but this one is essential info.
