kpdf: settings -> konfigure kpdf -> "Obey DRM restrictions

However this apparently works only for the 'traditional' DRM stuff (I'm
on lenny).

- From Adobe's web site:

it appears this 'feature' is only available for Wind0w$ and Mac l00sers.

I guess you are out of luck here.

Since it appears to contradict the mission of the British Library [1]
that the part of the population that uses linux and/or other OS is
excluded from this service, I would complain directly. I don't think
this will solve your problems in the short term, but hopefully in the
long term...

YMMV, good luck,
