Suspend broken (6.99.40, swcrypto)

[Jukka Ruohonen <jruohonen%iki.fi@localhost>]

Hello.

# sysctl -w hw.acpi.sleep.state=3

is (trivially) broken due:

        Devices without power management support: swcrypto0.

I think there were some recent refactoring-like changes in this department.

Since this happens ever so often, I'll write a test case for this once I get
the sources sorted out, but in the meantime, please add the dummy hooks.
