Basically, it's just a userspace re-implementation of megi's power management driver, with an mguard-like feature for modem recovery (force disconnect/reconnect the modem if it doesn't come back online after suspend).
This also means it can be used with any kernel, except megi's as it conflicts with its own modem management driver.
