-2 is -ENOENT (no such file or directory). ipw2000 requests its firmware
using a hotplug event, but when the driver is compiled into the kernel
it gets loaded _before_ the root fs is mounted and of course the hotplug
system and the firmware are not available.

I suggest to stick with modular driver, otherwise you must create an
initrd with hotplug + firmware.
