    Avlab(!) claims to support Linux, See !

    These instructions are incomplete at best:
    - Linux would be prefer using I/O A000/A400 (in your example), please don't reprogram
      the BAR's (as the example given would clash with an existent port at 0x278!)
    - They show 18 different models, but don't give BAR mappings for all serial/parallel
      register sets (BAR = Base Adress Register, see PCI Standard).

    You could probably politely ask support for documentation. I would help to
    get these supported out-of-the box in Linux, it's just a matter of adding
    some lines to a table (as shown by tim).
