Hello Dennis,
the 802.3at alias POE plus has been just approved in this mounth.
However, it is already mentioned in some documents describing POE modules and capabilities
look for Enhanced POE on CCO you should find documents about C3750 for example.

Q. Will Cisco support the IEEE 802.3at (PoE+) standard when it is finalized?
A. Absolutely. Cisco is a proponent of and major contributor to the IEEE 802.3at standard. Cisco Enhanced PoE does not replace or compete with the IEEE 802.3at (PoE+) standard. Cisco will support the standard after it is ratified, which is currently scheduled for 2009.

It may be too early to have them but it should be just a question of time.
Hope to help
Giuseppe
