insmod tulip kernel mismatch

["Gary Manigian" <gm@designconcepts.net>]

I'm setting up a new system.
I upgraded from a 2.2.x kernel to 2.4.18-bf2.4 kernel.
There are 2 Ethernet interfaces; eth0 is working.
The 2nd is an SMC 1255TX PCI card; I downloaded the driver from
the SMC site.
Installed kernel-headers-2.4.18-bf2.4; copied the include files
to /usr/src/link/include.
Ran make; copied tulip.o to
/lib/modules/2.4.18-bf2.4/kernel/drivers/net.
Then cd /lib/modules/2.4.18-bf2.4/kernel/drivers/net.
Insmod tulip returns:
kernel-module version mismatch
tulip.o was compiled for kernel 2.4.18
while this kernel is version 2.4.18-bf2.4

Any help would be appreciated
Thanks in advance.
