RTL8139 vs 8139too Netcard

Hi, Got a little problem here in settings of my ethernet card. When booting with 2.2.18 I have to configure the card as rtl8139 When booting with 2.4.2 I have to configure the card as 8139too Is there some fix or is there a possibility to make some alias arangment in modules.conf so that when booting a kernel, it chooses the right alias. TIA. Filip.
