The pcm driver doesn´t seem to detect the Realtek AC97 onboard audio on my Mobility Radeon 9000 IGP motherboard.

I tried the regular way, device pcm on kernel/build/install/reboot and didn't work, i tried with and without options PNPBIOS, with and without sbc, with and without all the other drivers in all the possible combinations, i tried loading sound modules(pcm/sbc/ich/all) after boot, before boot, i tried the sh MAKEDEV snd0 thing after all the above and it didn't work.
