2.6.5 - incomplete headers?

[Axel Weiss <aweiss@informatik.hu-berlin.de>]

Hi,

I'm going to bring my device drivers[1] from 2.4 to 2.6 and have successfully 
installed kernel-2.6.5 for my athlon-PC.

Compiling (unmodified) 2.4-sources of my modules stops, missing irq_vectors.h.

What do I have to do to successfully include <linux/interrupt.h> from inside a 
kernel module? Or is ther a completely different strategy for ISRs in 2.6? 
(Where is the starting point to read, in this case?)

FYI:

$ uname -r
2.6.5

$ gcc -c -Wall -I/lib/modules/`uname -r`/build/include -DMODULE -D__KERNEL__ 
-DHARMONIE_DEBUG harmonie_io.c
In file included from /lib/modules/2.6.5/build/include/linux/irq.h:20,

                 from /lib/modules/2.6.5/build/include/linux/interrupt.h:11,
