You write a custom hook that does restart your services. How to write such
a hook is described for example on http://en.opensuse.org/Pm-utils
I would write one hook per service, and then you can easily enable / disable
them by setting their executable bit.

I think, but have not tried it, that you can put your config file "myconfig"
into /etc/pm/config.d, make it executable and just put

SUSPEND_SERVICES="foo bar baz"

into it. Then in your hook /etc/pm/hooks/42myhook you should be able to
use $SUSPEND_SERVICES.

If that does not work, it would be a bug, IIUC.
