and 6 months in to that 9 months you bring out the next CPU Card, and
the next, and the next, and the next, and the next.
there's a hell of a lot of history already behind the EOMA
initiatives. i'm running this discussion down, btw - the point's been
made, and i'm inviting linux kernel developers who may not have been
aware of the initiative to be involved.

you've missed the point. EOMA-68 CPU Cards are separately-sold
mass-volume *interchangeable* products, i.e. being packaged in legacy
PCMCIA housings they have the exact same advantages of PCMCIA except
now it's the *CPU* that's interchangeable between products.
nobody in their right mind swaps the DVD electronics, they just buy
another DVD player. including the mechanical part and the built-in
PSU, and the GPL-violating software running on it.

that's probably enough.
