One thing I forgot to add (I was typing on a telephone) was that in
case of pcscd you can use the extended APDU, but only if you're using
the proprietary driver from OmniKey (pcsc-omnikey in Debian/Ubuntu
non-free, for example). If gnupg goes through the psccd, this could
allow you use of larger keys. A useful page for you should also be (the
"CCID/ICCD readers" section):
http://pcsclite.alioth.debian.org/ccid.html
This driver collides with libccid, btw, so only one of those can be
active at the same time. The proprietary driver also provides the
contactless reader capability (almost nobody makes CCID-compliant
contactless readers unfortunately).
Best regards
