Two NICs shouldn't be a problem here.  Could you try the following patch? :

diff --git a/src/arch/i386/drivers/net/undionly.c 
b/src/arch/i386/drivers/net/undionly.c
index c38b574..abb839b 100644
--- a/src/arch/i386/drivers/net/undionly.c
+++ b/src/arch/i386/drivers/net/undionly.c
@@ -58,6 +58,7 @@ static int undibus_probe ( struct root_device *rootdev ) {
 	/* Check for a valie preloaded UNDI device */
 	if ( ! undi->entry.segment ) {
 		DBG ( "No preloaded UNDI device found!\n" );
+		DBG_HDA ( 0, undi, sizeof ( *undi ) );
 		return -ENODEV;
 	}
 
Thanks,
