:Can the GPL'ed driver be used as documentation? You only need to know
:which bits to twiddle to make it go. Needless to say, the dfly driver
:should be coded from scratch in a cleanroom-kinda-way.

:But indeed, just plonking in an intel fxp card or somesuch does the
:trick too :)

:Cheers,

    In fact comments in the GPL driver state that it was developed from
    a cleanroom reverse engineering of the PCI card's registers.  It
    should be possible to dig up the original reverse engineered register
    set.

    I can't do this myself but I think there are some FreeBSD people 
    interested in doing it, who hopefully got the email I sent them despite
    my posting to freebsd-hackers getting stuck in the list manager's queue
    due to the new security thing they've instituted on the freebsd lists.
    I don't think they were aware of the GPL'd linux driver.
