[GTA-04] multiboot with QtMoko/SHR

[A.dre]

Thanks for your quick response. I will try an entirely different 
partitioning scheme (omitting the FAT32 on p1).

Still puzzled as why my SHR on p4 never booted.

As for 'unofficial beagle board pages', I was redirected there by [7]:
  "The SD card needs to have a special format as described here."
(Probably I misinterpreted something here(?).)

Thanks again, André.
