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.
