There are two bugs in the code I sent out...

case 0x01: /* 16K buffer size */
	ia->ia_maddr = 0xCC000;
	ia->ia_msize = 0x4000;  <---- there was an extra 'x' in 0x4000
	break;
	<Omit bunch of code>
   default:
	printf("ie: An EtherExpress 16 was detected but memory-mapping is turned off.\n"); <--- Needs a quotation mark at end
