    Not nearly as surprised as I was by your note.  It
    turns out that I was confused by my recollection of the
    DRAM memory chip vs. the bank size, and our wealth of
    product literature that supported my confusion.

    We haven't tested it, but the chipset will support up
    to 2 GByte if both banks are stuffed to the limit.

    It is still true that there are new memory chips with
    geometries that are not supported by the ALI chip, so
    there is some chance particular DIMMs might not work.

    Also, the L2 cache tag only supports 512M worth of 
    memory, so anything beyond that will only be cached in
    the on chip L1 cache.

    For general consumption - note that we have not tested
    any configurations beyond 512 MB, so we do not have a
    list of approved vendors.
