I tried the metzlerbros driver (1.1.7) and got some interesting
results. With the original one I was not able to compile the modules:

gcc -D__KERNEL__ -I/usr/src/linux-2.4.21-166/include  -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -fno-unit-at-a-time -pipe -msoft-float -mpreferred-stack-boundary=2 -DMODULE -DMODVERSIONS -include /usr/src/linux-2.4.21-166/include/linux/modversions.h -I.. -I. -g -DUSE_OSD -DDVB_KNC -MD -I../../include -nostdinc -iwithprefix include -DKBUILD_BASENAME=saa7146_core  -c -o saa7146_core.o saa7146_core.c

But I found a patch for this problem at
http://www.j-pfennig.de/zapdvb/download.html. Now it seems to compile
the modules. I'll report about the results later.

Not yet. If possible I would like to find a solution with my current
kernel cause I don't want to change an almost running system.
