You don't have to be root for compiling the driver.  The root priv is
needed only for installation, i.e. make install.

Interesting.  You're using 2.6.20 kernel, right?

First check include/config.h. whether it defines
CONFIG_HAVE_INIT_UTSNAME.  If it's defined, then the build must go
well.  If it's undefined (commented out), then check configure.in
whether the patch was properly applied and -Werror was changed to
-Werror=implicit-function-declaration.  And see config.log at the
place where init_utsname is checked.  You must have a compile error
there.  Show that part.
