That's what I saw, too. It gets funny when you boot with a 800K disk
inserted: The driver "detects" *two* floppy drives with an unsupported HD
disk in each. Maybe you could try that and see whether the driver does
anything useful afterwards, just to see if there is a fundamental
misunderstanding or simply an initialization issue?

For the LKM, you need only the machdep.c patch, which provides a variable
that holds the IWM base address.

You need to untar the "iwm.tar.gz" from above the sys dir (usually in
/usr/src) - look at "tar -ztf iwm.tar.gz".

Then you need to patch your sources by issuing "patch <1-3-2-iwm.diff" from
./sys/arch, run a config GENERICIWM and compile.
