The X200 uses ACPI. ACPI suspend is still work in progress afaik. Last thing i read about it is that suspend kind of works in some cases, but the resume part doesn't...
The X30 is an APM system, so that doesn't realy work for the X200. I don't miss suspend/hybernate support on my X200 - iirc Theo and some other dev are using 40-series Thinkpads which use APM, so they have working suspend. If i missed the crucial acpi-suspend-works commit, i'd be glad to be corrected. - Robert
