Building with kernel-headers 2.4.25 fails

Hello list!

I'm new to buildroot and want to use it to compile some applications for an embedded arm device which is using uClibc 0.9.26 and kernel 2.4.26.

Now i want to compile openvpn for that target, but since a couple of days buildroot isn't supporting kernel 2.4.x anymore. The compile process stops at:
make: *** No rule to make target '/home/crossdev/buildroot/dl/linux-2.4.25.tar.bz2', needed by `/home/crossdev/buildroot/toolchain_build_arm_nofpu/linux-2.4.25/.unpacked'.

Stop.

Will it ever be possible to compile kernel 2.4.x or is it removed until now and will never come back into buildroot?
Or is there another - better - way to compile the toolchain and openvpn for my emmbedded target?

Sorry, but i'm a really novice user in cross compiling.

Thanks for any suggentions.
