In 2.6.x, modules are named *.ko, and you 'insmod|modprobe *.ko'.

To have *.ko built correctly, read and use
./Documentation/kbuild/{modules.txt,makefiles.txt}.

Here is a working trivial makefile for out-of-tree simple modules:

# makefile for oops_test/dump*.c
# Randy Dunlap, 2003-03-12
# usage:
# cd /path/to/kernel/source && make SUBDIRS=/path/to/source/oops_test/ modules

obj-m := dump_test.o

# end;

Yes.

| /usr/sbin/insmod -v
| module-init-tools version 3.0-pre1
| 
| /sbin/insmod -V
| insmod version 2.4.18
| ....
| 
|

| 	....
| 	root@dimension#
| 
| I'm using module-init-tools-3.0-pre1, gcc3.0.4, kernel2.6.0

Make sure that the module-init-tools binaries are in $PATH
for user=root (and before the older ones if both are there).
