    I bought this notebook quite recently and used on it
    2.6.21-rc7[-mm[1|2]] and with all this kernels memory suspend doesn't
    work, but on my previous 'acer' machine it worked quite good.

    Today I have tested memory suspending feature on ubuntu 2.6.17 and
    vanilla 2.6.20.
    It doesn't work properly too with both this kernels.
