Lesenswert?

Ich habe einen DIL/NetPC9200 und versuche gerade das Demobeispiel ssvirq 
zu compilieren. Leider bekomme ich folgende Fehlermeldung:

zeiro@6715b:~/test4$ make
/usr/local/arm-linux/bin/arm-linux-gcc -D__KERNEL__ -DMODULE 
-march=armv4 -mtune=arm9tdmi -I/usr/src/linux-2.4.27-vrs1-ssv1/include

-fno-strict-aliasing -fno-common -mshort-load-bytes -msoft-float -c 
ssvirq.c -o ssvirq.o
ssvirq.c: In function `ssvirq_init':
ssvirq.c:90: `AT91PS_SYS' undeclared (first use in this function)
ssvirq.c:90: (Each undeclared identifier is reported only once

ssvirq.c:90: parse error before `AT91_SYS'
ssvirq.c:94: `AT91_SYS' undeclared (first use in this function)
make: *** [ssvirq.o] Fehler 1

wie kann in nun herausfinden in welcher Header-Datei sich AT91_SYS 
befinden soll?
