The .config is basically the same as used previously with 2.6.10-rc3-mm1-V0.7.33-04 (Ingo's realtime patches) without problems. [though I expected & saw plenty of unused symbols when I did make mrproper / xconfig for 2.6.10-mm1] To fix this, should I just add the EXPORT_SYMBOL lines for these symbols snd_ac97_restore_status snd_ac97_restore_iec958 or is something more needed?
