checking atags for boot parameters

[Christopher Harvey]

 I'm suspicious that the bootloader I'm using isn't passing atags to the 
 kernel properly.

 I'm getting a prefetch exception right after the "uncompressing 
 linux....done" message, does it make sense that this could happen 
 because mem=128M isn't getting passed properly?

 Basically what I want to do is have the kernel print out the boot 
 parameters along with the "uncompressing linux" message.

 thanks,
 Christopher
