Sorry, I was wrong about the device numbers, the driver is known to work with 
the following devices:

    db_printf("PCnet ID 0x%04x (%s) ",
                val, 
                (0x5003 == val) ? "Am79C973" : (0x7003 == val) ? "Am79C975" : 
"Unknown");

You should modify the folowing function in the if_pcnet.c file to make it 
work, if it doesn't:
	pci_init_find_pcnet( void )..

 But unfortunatly there's another bigger problem. There is no HOST PART of the 
PCNet driver for the PC in the eCos repo!!!. You should write one Yourself.
 
 You can help yourself with my HOST PART for the VMware driver, because it has 
all the functions the PCNet requires.
You can dovnload the VMware patch from 
<http://www.ecos2.vsr.si/patches/vmWare-net.html>. 
Apply it then change the HOST PART at xxx/packages/devs/eth/i386/pc/lancepci/* 

Or perhaps (might be the easiest way) You can try to run my VMware driver as 
it is on Your board, there's a chance for it to run because it's essentially 
a crippled 79C790 driver ...
