    Okay, I've just spent a couple of hours browsing through the scsi code,
    compiling different configs, and trying to figure out what to do with
    the Makefile stuff.

    I can't seem to find a clean way of getting the drivers outside "drivers/scsi"
    to link _after_ the other low-level drivers. My linux Makefile abilities is
    limited though, so if someone with the knowledge would do what Eric requests
    above please. We will probaly have to move some thing around, and that would be a
    _bad_ move at this point I guess.

    Now as I see it we have a few things we also need to fix:

    Someone on lkm reported getting low on dma-pool memory when using scsi as
    builtin. Now Eric, how big is the difference between the two cases (module vs.
    builtin) in the old scsi code? We use the module case for allocating dma mem
    now. I guess the module case tries to alloc as little as possible in order to
    not hit fragmentated mem?

    The initialization routines needs to be looked at. Because we use the module
    stuff, some information gets printed wrong, like "scsi: 0 hosts" scrolling
    down the screen for each host.

    I begin to wonder if some of this _really_ is 2.5 stuff. If someone can come
    up with a clean solution to the Makefile issue, we might pull it off. If
    we need to move the other scsi drivers (i2o, etc.) around I think we should
    back off and do it nice and slow for 2.5. In this case we could revert to
    the point where sd/st/sr are modulized, and saving the core system for 2.5.

    This is just IMHO, let me know what you think.
