Michael,

Thanks for pointing me to those, that got me going (I used a combination 
of the with-linux kernel and the uinitrd from Slackware 13.37 to get 
everything installed).  You made my day getting my plug all ready to go!

Cheers,  Innes.

I circumvent the problem of an accidental upgrade (leading to an unbootable system) by mounting the partition that contains the custom uImage to /boot-vfat; /boot is just a folder. In this case a kernel upgrade will overwrite the uImage in /boot, which doesn't affect the system boot at all. Maybe not the best way, but it works. ;)
