two ethernet card's eepro100 don't work togheter

[=?ISO-8859-1?Q?Jo=E3o_Gabriel_Sapucahy_Chiste?=]

I tryed all the ways... changing the PCI slots, all the slots are 
working, changing the cards... But nothing works, i really need to make 
this work for my graduating work.

The drivers are compiled into the kernel 2.6.11.8
I tried passing arguments to boot, but it won't work until the system 
recognizes the two boards. When i do lspci only shows one always

Any help?????????
