    Hi Rui,

    I found the difference. The 2.4 kernel allows you to set the
    parameters dynamically (eg. RH7.2). The 2.2 kernel (as shipped with
    RH6.2 for example) does not. To set the parameters for the 2.2 kernel
    it's necessary to edit a file, probably called
    /usr/src/linux/include/asm/shmparam.h and rebuild the kernel.
