SUSE on Thinkpad600

I have just installed SUSE on my old Thinkpad 600. Everyting including the internal modem (after installing mwave patch) works fine. I have not managed to configure the sound card. Can someone help. ALSA did not find and cards, later it asked if I wanted to proble lagacy cards but again it did not find anything. Although, ALSA does did not configure anything the alsamixer (after running alsaconf) shows that the card CS4237B was detected and I could even play a CD but all this disappers when the machine is rebooted. This means that somethings is getting configured half way. Any help will be apprecited. bye Arvind
