@extendedping: I tried again calibre, and now it worked out of the box, perhaps due to some updates of the Debian squeeze distribution.

It takes some time to start, but once running, it's working well. See this youtube video if someone doesn't know yet what calibre is good for (I didn't).

CAVEAT: Like with eric4 (see post above), this needs the .kbdactive fix of the last easy-deb-chroot version for debbie keyboard focus, and moreover libpulse0 from squeeze. The latter breaks sound in Easy Debian, however. If you need sound in Easy Debian (I don't really), you may want to wait until somebody (qole?) could tell us what to do about it.
