A cool young fella by the name of Carsten Munk (@stskeeps) has put together a quick video demo showing how the Nokia N900 dual-boots between Maemo and MeeGo pretty seamlessly.
Carsten also states that:
MeeGo 1.1 isn’t out yet, give us a little bit of time. What will happen if things go right:
* Package install from extras-devel that enables the u-boot boot loader.
* Upon startup, if there is a SD card that’s bootable, it will boot the SD card, with MeeGo. Otherwise, it will boot Maemo.More customized setups are possible for the daring.

While MeeGo will not come officially come to the N900, there will be a community based version which will be installable with a brief tutorial. Follow the thread on Maemo Talk for more details.
