Questions on Linux T series models

[JonathanGennick]

Does anyone have one of the new T61s that are being sold with SLED preinstalled? Does sleep/wake work reliably? Hibernate? The volume buttons and function keys such as fn+home to brighten the screen? Are the various "Think" utilities available on the SLED platform?

Mostly I'm concerned about sleep/wake and hibernate. But I'd like to know whether all the other Thinkpad functionality is fully supported.
