[Bluez-users] old patches - where to get from?

I would like to get the patch to provide bluez bluetooth support for Kernel
2.4.21.
Some weeks ago this patch was available at bluez.org or
holtmann.org.Unfortunately it isn't anymore.
And can anybody tell me what this patch makes? I guess it provides support
for additional bluetooth devices as far as I kown for the AVM bluefritz usb
dongel?
Any other changes?

Another question: Why is the bluetooth bluez subsystem distributed in the
two folders drivers/bluetooth and net/bluetooth?
So at which location is what implemented?

Thanks,
