I think there's a good chance it will work. E.g. on most android devices this module can be compiled and loaded without replacing the kernel.

I'll try to compile the module and vpn in the next few days, if I find the time to do it.

There are multiple places on the net with downloadable tun.ko. I downloaded the one from the debian repository with identical kernel version (except a -2 added on -- lenny). It is not recognized by insmod though (wrong gcc version -- kindle needs 4.1). It is reported that both the kernel version and the compiler version must match /proc/version. My build environment has a newer gcc, so I will have to get gcc 4.1 and compile tun.o with that.

There are detailed instructions out there for building and installing tun.ko for devices that do not have it compiled into the kernel. It might need static linking to eliminate dependencies -- not sure...

Here is one such thread:

and another:

You should probably use the kernel sources for your kindle, rather than from the debian source repository, to build a loadable tun.ko.

@carstenx: Be sure to use gcc 4.1.

You need to use the kindle source code to built a cross-tool chain, more symbol related errors will occur unless you find what else needs to be used in the cross-tool chain, binutils, etc.

I'm building my cross-compile toolchain right now... Do you know which exact gcc version I need to use? If you have console access:
$ dmesg | head
should print the gcc version the kernel was compiled with.
