qpxtool does not work with the Linux kernel's new IDE/SATA
infrastructure (libata):

------------------------------------------------------------------------
The kernel included with Debian currently ships with libata disabled for PATA
devices. However, I built my own kernel since the old IDE drivers don't work
properly with my hardware (JMicron 20363).
Someone else had the same problem and reported it here:
http://lkml.org/lkml/2008/1/11/297
https://bugzilla.redhat.com/show_bug.cgi?id=428281
I'll attach a bugfix that works for me.
The cause of this problem seems to be the overloaded Scsi_Command []
operator in qpx_transport.h - it has a strange implementation which is
easy to use incorrectly, and qpxtool does get it wrong in various places.
