    Will then every d be passed as separate parameter to hotplug? It means agent
    has to deal with unknown number of parameters or are there always fixed
    number of devs? apparently not as max is 8 and in your example only 3 are

    If number is variable I guess better would be

    alias pnp:cXXXXXXdYYYYYYY[:YYYYYY...]

    i.e. put all devs IDs in one field; actually may be even separator is
    redundant as IDs have strict format to my knowledge.

    Then hotplug agent gets two parameters - PNPID and PNPDEVS - and it is quite
    easy to build alias.

    can you give example how entries in sysfs look like (I do not have any ISA
    card). Is it possible to list them in the same order as in pnp_card_device_id
    table? Otherwise coldplugging becomes quite complicated. coldplugging script
    has to build the same string as hotplug invocation gets.

    Oh, BTW, what are those `@' in your example? If they mean single char
    wildcard, you should build them using `?' because modprobe is using normal
    fnmatch to match module name against aliases.

    thank you
