PC speaker stopped working after upgrade to Squeeze


When I upgraded my Lenny AMD64 system to Squeeze earlier this year, the
PC speaker (ie motherboard buzzer) stopped working. To get it to work I
have to remove and re-add the pcspkr kernel module using modprobe every
time I reboot. The only relevant bits I can find in dmesg are:

[    2.616528] udev[376]: starting version 164
[    2.861193] input: PC Speaker as /devices/platform/pcspkr/input/input2
[    2.904056] ACPI: WMI: Mapper loaded

during boot, and:

[  885.175967] input: PC Speaker as /devices/platform/pcspkr/input/input8

when re-inserting the module.

There is also:

[    4.117058] hda_codec: ALC889A: BIOS auto-probing.
[    4.118461] input: HDA Digital PCBeep as
[    4.122153] HDA Intel 0000:01:00.1: PCI INT B -> GSI 19 (level, low)
-> IRQ 19

Is that relevant?

My kernel is currently linux-image-2.6.32-5-amd64 2.6.32-37 and the
motherboard is a Gigabyte GA-MA790FXT-UD5P.

Why do I need to reload the pcspkr module? Is there any way I can get it
to work from boot? Is this be a kernel or udev bug, or just a weird
hardware / software configuration combination?

Thanks for any help,
