I'm using u-boot with a configuration header, and there I have set the 
new CTRLA, CTRLB and RFR values (and I did compare the values with the 
Micron data sheet; apart from the TCKE value they are all identical).

But are you saying that the values set by the boot loader are preserved 
by the kernel?  (In that case I wonder what the sdram-micron header file 
is for :)


Thanks,
Orjan
