The smc91x driver doesn't seem to pull its parameters from the netdev=
parameter. Instead, a `platform_bus' is used, which requires a call to
`platform_add_devices' -- an example of this below. Could the smc91x
driver be modified to pulls its parameters from netdev=?

Cheers,
Shaun

#include <linux/device.h>

static struct resource smc91x_resources[] = {
	[0] = {
		.name	= "smc91x-regs",
		.start	= 0x300,
		.end	= 0x30f,
		.flags	= IORESOURCE_MEM,
	},
	[1] = {
		.start	= 17,
		.end	= 17,
		.flags	= IORESOURCE_IRQ,
	},
};

static struct platform_device smc91x_device = {
	.name		= "smc91x",
	.id		= -1,
	.num_resources	= ARRAY_SIZE(smc91x_resources),
	.resource	= smc91x_resources,
};

static struct platform_device *devices[] __initdata = {
	&smc91x_device,
};

void __init pathport_init(void)
{
	platform_add_devices(devices, ARRAY_SIZE(devices));
}
