    SubjectRe: Potentially dead bttv cards from 2.6.10
    Thanks for the hints.  Unfortunately the cards in question really are 
    fairly generic and thus don't appear in the list. I tried the first 75
    cards as insmod options (using a script of course), and some of them are
    different, but none work properly.

    I am lucky in that I still have a spare. If you could suggest a very
    well tested kernel for bttv (2.6.9?), I can set up another machine with
    that kernel and the remaining card. That should allow me to isolate the
    problem better. At the very least I could get the right card= option
    to use for the broken pair. Hopefully I will be able to generate a
    table entry for this card for bttv-cards.c; I'll look some more at this
    tomorrow.

    I've heard that there is some way to dump eeproms; Is there a way to
    write them also? If I could copy the eeprom from the unused cards to
    the (now broken) pair that might fix things.

    Thanks,
    Jim
