I'm just assuming it isn't a device driver. Sonja (the original poster)
just mentioned 'a kernel module'.
It might be worth asking what exactly this module does and why it would
need to be implemented as a kernel module if it needs so much memory.

If it's a device driver, what is it driving? The only hardware that
springs to mind which might need large amounts of memory is a camera
driver or some high-speed sampling device.
