The only solution i found was a not anymore supported module for netfilter from Rusty Russell.
I tried to fix the compiler errors/warnings and finally it worked.
Usage:
ifconfig eth0 192.168.1.1
ifconfig eth1 192.168.2.1
arp -s 192.168.1.2 <hardware address of eth1> -i eth0
arp -s 192.168.2.2 <hardware address of eth0> -i eth1
modprobe ip_crossover dev1=eth0 dev2=eth1
Then doing ping 192.168.1.2, ICMP ping goes out eth0 and comes back in eth1.
ip_crossover.tar.bz2
for testing packets with differenz sizes i did:
for i in $(seq 0 1472); do ping -q -c1 -s$i 192.168.2.2 >/dev/null || echo fail $i; done
for i in $(seq 0 1472); do ping -q -c1 -s$i 192.168.1.2 >/dev/null || echo fail $i; done

Here is how i made the patch for inclusion:
git config --global user.name "Peter Holik"
git config --global user.email "peter AT holik.at"
check kernel out with git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
first i had to export usbnet_get_ethernet_addr from usbnet.c
and to fix cdc_ether.c
git commit -am "export get_ethernet_addr from cdc.ether.c in usbnet"
then copy my new driver int51x1.c to /usr/src/linux-2.6/drivers/net/usb/ and modify /usr/src/linux-2.6/drivers/net/usb/Kconfig and /usr/src/linux-2.6/drivers/net/usb/Makefile
git add /usr/src/linux-2.6/drivers/net/usb/int51x1.c
git commit -am "usb driver for intellon int51x1 based PLC like devolo dlan duo"
git format-patch -s origin/master
Then mail the created file to linux kernel mailinglist:
cat 0001-export-usbnet_get_ethernet_addr-from-usbnet-and-fixe.patch | \
mail linux-kernel@vger.kernel.org
cat 0002-usb-driver-for-intellon-int51x1-based-PLC-like-devol.patch | \
mail linux-kernel@vger.kernel.org
Many thanks to the guys at linux-kernel@vger.kernel.org for suggestions and improvements.
Undo last commit with git reset --soft HEAD^
My driver will be part of linux kernel 2.6.31

Clusterssh opens for each connection a xterm and sends a keystroke to each window.
You can also work in only one xterm.
#> apt-get install clusterssh
I use approxd for caching .deb's using port 9999. This port is not reachable by all my hosts,
therefore i use remote port forwarding from ssh.
I can type
#> cssh -o "-R9999:approxy:9999" host1 host2 host3
or create a default config
#> cssh -u > $HOME/.csshrc
You can define different clusters aliases. Each alias consists of some hosts:
clusters = apt monnow i only type
apt = host1 host2 host3
ssh_args= -x -o ConnectTimeout=10 -R9999:approxy:9999
#> cssh apt
a small patch makes "retile windows" working for me:

I could not run the ubuntu live installcd and also the alternate hang sometimes. After a successful install X freezes. I tried to boot with various boot options. Only with acpi=off my system seams to working but with fan running and no battery info. An older knoppix was running, so i decided to install older ubuntu kernels and saw my system running with a gutsy kernel (2.6.22) but not with a hardy kernel (2.6.24).
What changed inside the kernel?
After searching a lot i found pci=nommconf.
It seams that something in the way pci is configured has changed.
