This is the output from dmesg i think is relevant
[ 45.821410] input: PC Speaker as /devices/platform/pcspkr/input/input7
[ 46.109130] ACPI: PCI Interrupt Link [AAZA] enabled at IRQ 22
[ 46.109134] ACPI: PCI Interrupt 0000:00:10.1[B] -> Link [AAZA] -> GSI 22

[ 46.142474] hda_codec: Unknown model for ALC883, trying auto-probe from
BIOS...
[ 46.412242] lp: driver loaded but no devices found
Although it says no devices found it works in 2.6.24-11
The dmesg output from 2.6.24-12
lists a bunch of symbol not found snd:
Hope it was informative enough. Else i will fill in more info as
requested.
