For some reason my F-12 system is not seeing my floppy disk controller

ideas? F-11 finds the controller OK.
The solution turns out to be really simple. I did not have the floppy
drive hooked up when I did the install. As a result, anaconda did
not create the /etc/modprobe.d/floppy-pnp.conf file. With that file
in place, F-12 sees the floppy drive just fine at boot.
$ cat /etc/modprobe.d/floppy-pnp.conf
alias pnp:dPNP0700 floppy
alias acpi:PNP0700: floppy
The final glitch I had to fix is that all Linux kernels I've tried have
problems with DMA when writing to the built-in floppy controller on my
motherboard (ASUS M4A78T-E). The symptom is that the driver writes the
first 2 bytes and than hangs forever with the floppy motor running.
Workaround for that is to add "floppy=nodma" as a parameter to the
floppy module. That's almost certainly non-optimal (it applies to
reading, too), but I don't use floppy disks often enough to care. I
added a file in /etc/modprobe.d :
$ cat /etc/modprobe.d/floppy-nodma.conf
options floppy floppy=nodma
