Very Computer

I just tried to compile a new kernel on a totally fresh Linux SuSE 7.3 for
PowerPC and always had resulting errors.
The system is a Gravis TT (Umax Pulsar or S900) running a 2.4.12 kernel. I
tried to compile a kernel from the suse source tree of the 2.4.12 kernel, a
2.4.16, 2.4.18 and 2.4.19 kernel, they all ended up giving me errors when it
came to make modules_install.

The last lines of what make modules_install delievers are (this is for the
2.4.19 kernel):

cp: cannot stat `ipt_mark.o: No such file or directory
cp: cannot stat `ipt_tcpmss.o: No such file or directory
cp: cannot stat `ipt_tos.o: No such file or directory
make[2]: *** [_modinst__] Error 1
make[2]: leaving directory `/usr/src/linux-2.4.19/net/ipv4/netfilter
make[1]: *** [modinst_ip4v/netfilter] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.19/net
make: *** [_modinst_net] Error 2

I must say that I am very new to this all, but I need to make my own kernel
in order to be able to use my formac proformance video card (based on a
permedia 3 chip).

Can anyone help me and point out what I did wrong? Is it a wrong kernel
config, or incorrect kernel sources? I got mine from kernel.org.

Any help is greatly appreciated!
