bootz works here. bootm always complains with the scripts from the generic 
environment:

booting kernel of type uimage from /dev/ram0.kernel
Bad Magic Number

But:

me@host$ file arch/arm/boot/uImage
arch/arm/boot/uImage: u-boot legacy uImage, Linux-2.6.31-00770-g54c3fe6-dir, 
Linux/ARM, OS Kernel Image (Not compressed), 2350016 bytes, Mon Oct 25 
16:58:30 2010, Load Address: 0x40008000, Entry Point: 0x40008000, Header CRC: 
0x17A7330B, Data CRC: 0x888DAA63

Anything wrong with the uImage (built with "make uImage") or the 
command 'bootm'?
