You have to flash the kernel (only for the next boot) for meego, everytime you want to boot into it, until u-boot is working. Otherwise if you flash permanently, you are not able to launch Maemo (or NITdroid) until you revert to the stock kernel (or some of the others, you are using).
Instructions can be found at http://meego.com/downloads/releases/...o-v1.1-handset
