It seems that the driver.parameter syntax works only for parameters
that the driver exports in /sys/module/driver/parameters. The ne
driver doesn't define parameters at all when not compiled as a module,
let alone export them via sysfs.

The attached patch is my feeble attempt to remedy the situation. With
the patch, adding "ne.irq=9,10" to the kernel command line sets the
correct irqs for eth0 and eth1.
