What I would like to know is: What is at 0x3f0-0x3f1 on
your machine, and why does your PnP BIOS list these
two ioports as used by "system peripheral: other"?

On my ThinkPad 600, the BIOS lists 0x3f0-0x3f5 as owned
by the floppy device:
jdthood@thanatos:~$ sudo lspnp -v 08
08 PNP0700 mass storage device: floppy
irq 6
io 0x03f0-0x03f5
dma 2

It looks like there's a bug in your BIOS. What we could do is
patch the PnP BIOS driver so that it refrains from reserving

I'll let others comment on the appropriateness of your patch
to floppy.c . I don't know whether it's the right thing to
do or not.
