Problem with sis900.o on 2.4.21-99-default

Hi all! I've SuSe 9.0 professional installed in a Terminator Asus Pentium IV 2Ghz. Seem to be all right but my eth0 doesn't work even if the module "sis900.o" is setup succesfully. I tried to find out an update about "sis900.o" but nothing for my kernel : "2.4.21-99-default" .... Anyone may help me? Thank Paolo
