    VmallocTotal: 245752 kB
    VmallocUsed: 137720 kB
    VmallocChunk: 107904 kB

    Okay, i see the problem now, the largest piece of memory which could be
    allocated is 107904 kB, right?

    Is the 4G/4G split already in the kernel? If yes, which entry activates it?

    BTW, CONFIG_HIGHMEM4G is enabled already :-)

    Thanks for the hint!
