From an Intel document*:
Nokia Nseries Internet Tablets,
Among the early products anticipated to be powered by Intel WiMAX chipsets will be
the Nokia N800 series Internet Tablets, expected to ship in 2008. Running opensource
Linux, a Mozilla-based browser, and an array of popular applications, the device
will deliver full-featured Internet access through Sprint’s Xohm WiMAX network.

The Intel® WiMAX Connection product family includes the 2200, 2300R, 2320R and 2400 chips. The 2320R might be the most possible candidate for inclusion?
