    After a lot of swimming thru the mail search page, I found that there
    are a LOT of problems that have in common these items:

    1) rl0 interface
    2) FreeBSD5.3
    3) error messages of the form "rl0: discard oversize frame"

    There are a pretty fair number of these, from various sources. Fact.
    At least one of them claimed it was solved in RELENG_5. Sure wish I
    could locate the other mails in THAT chain (I spent 20 minutes trying to).

    So my fix sounds like it boils down to one of two items: either getting
    someone who knows 5.3 better than I do to recommend a cardbus device
    that would be sound (a vendor) and I would run right out and buy it, or
    I suppose I could get the required sources burnt onto a cdrom, and get
    them on that laptop that way, recompile, and see about reinstalling.

    I am loath to try that second method only cause I have all that userland
    software that I mustn't lose compatibiilty with, and it's got all those
    dependencies (sleepycat database, python, gtk, 3 1/2 pounds of my
    coding). I want to do the minimum necessary to get it working.

    So, if one of you folks can recommend a cardbus card that I oughta buy,
    that doesn't use the rl0 driver, that would be nice. mail me a *.ko for
    it, and I would love you forever. Skip that last part if you want,
    cause maybe I could do it, but I wasn't joking about wanting to mess
    with this the least I can, it's a fragile stack of software.
