    The laptops use the Turion chip. According to AMD, the Turion's
    integrated memory controller can use PC1600, PC2100, PC2700 or PC3200
    unbuffered DDR SO-DIMMs and has a maximum throughput of 3.2 GB/s.

    So, explain to me what engineering in dual channel support is going to
    buy you. BTW, does any vendor manufacture dual channel compatible
    SO-DIMMs?
