Dynamic linking of kernel module bug?

[Seshaprasad V]

I am facing an issue, which I feel has something to do with the dynamic
linking runtime support in linux for loadable kernel modules. Following
is a description of the issue:

I have a module which has an extern variable. The variable is declared
in a statically linked part of the kernel(linux). When i try to
load the module(using insmod), i get an unresolved symbol error. However
when the driver is statically linked, i don't get the error. 

Any clues will be appreciated.

Thanks,
Sesha
