    Actually if you wish you can use your full 1GB just fine without HIGHMEM:

    In /proc/meminfo:
    MemTotal: 1025360 kB
    LowTotal: 1025360 kB

    At boot:
    kernel: On node 0 totalpages: 262128
    kernel: zone(0): 4096 pages.
    kernel: zone(1): 258032 pages.
    kernel: zone(2): 0 pages.

    The related config parameters:
    CONFIG_NOHIGHMEM=y
    # CONFIG_HIGHMEM4G is not set
    # CONFIG_HIGHMEM64G is not set
    # CONFIG_1GB is not set
    CONFIG_2GB=y
    # CONFIG_3GB is not set

    For what I know this trick just limits you on the amount of swap you can
    have. The suggestion came from Ingo Molnar and it works fine for me.
