kernel-tmb-laptop-2.6.23-0.rc8.1mdv:
        The kernel package contains the Linux kernel (vmlinuz), the core of your
        Mandriva Linux operating system.  The kernel handles the basic functions
        of the operating system:  memory allocation, process allocation, device
        input and output, etc. This kernel is compiled for laptop use, single or
        multiple i686 processor(s)/core(s) and less than 4GB RAM, using HZ_100
        to save battery, voluntary preempt, CFS cpu scheduler, cfq i/o scheduler
        and some other laptop-specific optimizations. If you want to sacrifice
        battery life for performance, you better use the kernel-tmb-desktop.
        This kernel relies on in-kernel smp alternatives to switch between up & smp
        mode depending on detected hardware. To force the kernel to boot in single
        processor mode, use the "nosmp" boot parameter.

        The tmb kernels is an experimental kernel based on the kernel.org
        kernels with added patches. Some of them may/will never end up in
        the main kernels due to their experimental nature. Some refer to
        this kernel as a 'hackkernel' ...
        Use these kernels at your own risk !!

kernel-tmb-laptop-devel-2.6.23-0.rc8.1mdv:
        This package contains the kernel-devel files that should be enough to build
        3rdparty drivers against for use with kernel-tmb-laptop-2.6.23-0.rc8.1mdv.

        If you want to build your own kernel, you need to install the full
        kernel-tmb-source-2.6.23-0.rc8.1mdv rpm.
