    I'd call the AMD64 support in fairly poor shape right now.  I think
    the boot-loader does understand 64 bit kernel binaries but the kernel
    needs a lot of work to actually boot in that mode.

    I have been working around the edges... for example, my vkernel work
    also entailed continuing the cpu/platform separation work.  So it
    should be easier now then ever before for an interested party to begin
    a port.  A great deal of pmap-layer separation work has also been done
    as part of that work.

    I have to start thinking about the July release.  At the rate I'm going
    I am not going to have either the storage layer or the filesystem ready
    for the upcoming release.  It just isn't fun to work on one thing for
    6 months :-(

    AMD64 might actually count as low-hanging fruit with regards to
    getting something major done for the release.  All my boxes are 64 bit
    boxes running in 32 bit mode now so it isn't as though I don't have
    the hardware.  I really have to think about it.
