Here's the output:

mhzc_alloc_ethernet: iobase = 2800, iosize = 800, maxaddr = 3000, addr = 2800

Does that tell you anything?

I was messing around in this code yesterday, but I don't really know 
what I'm doing.  The comment from the mhzc_attach function reads in 
part:

	 * Once we have the Modem's address established, we search for
	 * an address suitable for the Ethernet portion.  We do this by
	 * rounding up to the next 16-byte aligned address where 0x80
	 * isn't set (the SMC Ethernet chip has a 16-byte address size)
	 * and attemping to allocate a 16-byte region until we succeed.

I inserted some debug printfs to see what was happening in the 
mhzc_alloc_ethernet for loop.  It seems to find a good portion of the 
address without the 0x80 bit set, but none of those have a 
successful pcmcia_io_alloc.
