You should check:

1) that you're compiling against the same linux headers of the linux
kernel you're using.

Use uname -a to get the linux kernel in use, and verify that the
headers used during compilation are the correct ones. On a
Debian/Ubuntu based system for each pre-compiled linux-image package there is
a corresponding linux-headers package, eventually install it.

2) that you don't have a conflict with some already installed
module. For example I experienced this when installing the v4l-dvb
modules which conflicted with the old standalone gspca module (gspca
V1). Since you can't have both installed you have either to remove the
old module and reinstall the v4l-dvb modules either to remove the
v4l-dvb modules and reinstall the old standalone module.

Unfortunately I think there isn't a make uninstall rule, so I think
the only solution to revert a system is to reinstall the kernel
(easily done with a package management).

HTH, regards.
