You should run "/etc/init.d/hotplug stop" before suspending and
"/etc/init.d/hotplug start" after suspending. It could be done via
script in /etc/acpi.
How do you switch to suspend-to-disk?
# echo disk > /sys/power/state
or anything else?

Probably the same like above.
Stop ALSA with "/etc/init.d/alsa stop" and start it after resuming.
