Manual kernel parameters are being ignored

Manual kernel parameters are being ignored

[Guillaume Dargaud]

Anyone care to tell me why the parameters I type manually for the kernel are 
being ignored ?

Linux/PPC load: console=ttyUL0,9600 root=/dev/xsa2 rw ip=off
Uncompressing Linux...done.
Now booting the kernel
[...]
[    0.000000] Kernel command line: console=ttyUL0,9600 root=/dev/nfs rw 
ip=on nfsroot=192.168.1.185:/ht

Care to tell us which kernel you are using and what your .config for it
looks like?

Sure, sorry for not giving more details, I thought it was kind of a general 
kernel question (and almost off topic here I must confess).

Kernel 2.6.24 from the Xilinx git tree.
Xilinx ml405 board, using UartLite console.

If I don't select CMDLINE_BOOL I can type in whatever I want, but if I set a 
CONFIG_CMDLINE then what I type is ignored.
