Asterisk with 2.6.16 Kernel

Im trying to set up an Asterisk server an an Debian system with an 2.6.16 kernel. My ISDN card is a Sitecom DC 105 V2. I’m trying to start with the bristuff-0.3.0-PRE-1l.tar.gz file.
after installing zaptel-1.2.3 and libpri-1.2.2 without any problems the qozap produces an error:

/bristuff-0.3.0-PRE-1l/qozap/qozap.c:914: error: âstruct zt_chanâ has no member named âmaxbytes2transmitâ
make[2]: *** [/bristuff-0.3.0-PRE-1l/qozap/qozap.o] Fehler 1

install: Aufruf von stat für âqozap.koâ nicht möglich: Datei oder Verzeichnis nicht gefunden
make: *** [installlinux26] Fehler 1

when I’m trying to install cwain and zaphfc I recive the same error.
Can samebody help me with my problem? THX
