I'm attaching a new version of isapnp.rc and a companion aliases file
to be installed as /etc/modprobe.d/isapnp (because this is easier than
writing the kernel patches needed and waiting for Linus to accept them).

The purpose of isapnp.rc is to automatically load the driver modules
needed by non-PCI hardware devices like floppy and rtc to allow udev to
create the /dev nodes.
It only supports 2.6 kernels, but this is probably acceptable because
older kernels do not support udev and can use on-demand modules loading.
(Older versions tried to support 2.4 kernels but this proved very hard
if not impossibile because tools in /usr/bin were required and the
script became too much complex.)

I'm going to add it to the next release of the debian hotplug package.
Comments are welcome.
