via82xx & acpi -> freeze bug

[Pavel Kysilka <goldenfish@bsys.cz>]

	Hi all,

i have via82xx based onboard soundcard.
i test toady new kernel 2.6.1-rc2 with suspend to disk (echo 4 > sleep).
my computer totally freeze with loaded module snd-via82xxx. if this
module not loaded, suspend to disk working with no problem.
kernel 2.6.10-rc1 working with this feature ok.

i rewrite by hand this lines (no information in log).
