Hi,

something is wrong with 34-01 and ALSA:

make modules_install gives me:

if [ -r System.map ]; then /sbin/depmod -ae -F System.map  2.6.10-mm1-V0.7.34-01; fi
WARNING: /lib/modules/2.6.10-mm1-V0.7.34-01/kernel/sound/pci/ac97/snd-ac97-codec.ko needs unknown symbol snd_ac97_restore_status
WARNING: /lib/modules/2.6.10-mm1-V0.7.34-01/kernel/sound/pci/ac97/snd-ac97-codec.ko needs unknown symbol snd_ac97_restore_iec958

and consequently after booting into the kernel modprobe'ing the alsa
modules fails:

~/tmp/src/linux-2.6.10-realtime-preempt-2.6.10-mm1-V0.7.34-01$ sudo modprobe snd_cs46xx
