If you enable this you will need a firmware file as well.
You will need to copy this to /usr/lib/hotplug/firmware/isl3890.
You can get this non-GPL'd firmware file from the Prism54 project page:
You will also need the /etc/hotplug/firmware.agent script from
a current hotplug package.

Note: You need a motherboard with DMA support to use any of these cards

If you want to compile the driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read Documentation/modules.txt. The module
will be called prism54.ko.
