Hi!

Yes, I have patched the kernel with this: 
/usr/src/xenomai/scripts/prepare-kernel.sh --arch=x86_64 
--adeos=/usr/src/xenomai/ksrc/arch/x86/patches/adeos-ipipe-2.6.37.6-x86-2.9-02.patch 
--linux=/usr/src/linux

xenomai being a link to xenomai-2.6.1 -directory. When I switch between 
Xenomai 2.5.6 and 2.6.1 I remove the whole linux directory and extract 
it from the source again and change the xenomai link accordingly. With 
Xenomai 2.5.6 the patching was done with this: 
/usr/src/xenomai/scripts/prepare-kernel.sh --arch=x86_64 
--adeos=/usr/src/xenomai/ksrc/arch/x86/patches/adeos-ipipe-2.6.37-x86-2.9-00.patch 
  --linux=/usr/src/linux
