Hmmm. The file that I downloaded recently is acpica-unix-20061109. It seems
to be quite old. There are some differences between the contents
of that archive and the acpi files in the kernel. I hope I really got the right version.

Ok. The new patch can be found in this message.
I tried to figure out where to put the definition of the ARRAY_SIZE macro.
I searched a little bit in the include directory, but I couldn't find a place
that satisfied me to a hundred percent. I chose acpi.h, because this
seems to be file that is most general. The problem is, that the file
only consists of lines that include other header files and the newly added
definition for ARRAY_SIZE breaks this consistency in some way. Perhaps
Len could give me a hint where to put it.
Ok, here's the new patch:
Diffed against the intel acpica implementation "acpica-unix-20061109".
Tested by compilation.
