2.6.22 kernel and 'alps_process_byte'

On the R500 (and other laptops, apparently) kernel 2.6.22 (and a few before, and a few after) panic on resume with an oops like the following:

[113189.828000] EIP: [] alps_process_byte+0x18/0x60 [psmouse] SS:ESP 0
[113189.828000] <0>Kernel panic - not syncing: Fatal exception in interrupt

Recompiling without extra alps support does not help.

Adding the module 'psmouse' into the MODULES variable in /etc/default/acpi-support seems to work -- no crashes so far. (Update 3/21: still no crashes! We have a winner)
