ACPI driver version 2.0.2 has been released (12/15/2005) on the eComStation Betazone. Advanced Configuration and Power Interface (ACPI) is a replacement for APM, PnP, and related hardware features. Apparently a future version of XWorkplace will support shutting down via ACPI. The latest version of the driver features support for multiprocessor systems (SMP, Dual Core, and HyperThreading).
