In the meantime, I had the chance to test a bit on a Debian
x86_64 box (AMD Sempron) and this one had no problems.
I've tested with a HP2200c, scanimage and xsane - nothing.
I've recompiled the current CVS stuff - no problems so far.
I did the tests also with my LiDE20 and LiDE30  - also
no problems. Tests have been done with and without the
calibration cache.

Ciao
