Sorry if i'm annoying you, but now it worked. :)

After i read "build" how you mentioned i found the problem why no
modules tar.gz were created. The build script needs a second parameter
to create the archive where the parameter can be whatever. I don't know
why this check is build into the script but with help of that it worked.
Second problem was that i had to copy the .config into the dummy
directory and not the linux-2.6 dir to be found.
The problem is that the info on the toolchain wiki [1] is a bit wrong
concerning kernel compiling. So i added a remark with the right steps on
this page.

I updated my fso-frameworkd with help of the patch from [2] and copied
the kernel and modules to the right place. Than i booted with the new
2.6.28 kernel but it didn't work at the first try.

I have a 64MB swap file activated in /etc/fstab which lies on the third
vfat partition of my sd-card. And at the point where the message
"activating swap partitions" came it hung and showed an error message
after 120sec timeout. So i thought that vfat wasn't working at boot time
and i disabled the swap file.
Next boot goes through and the freerunner started without any suspicious
error messages. After it booted the sd-card was mounted what means that
vfat should work. I had the same problem with the swap file a few weeks
ago with an older andy kernel and i don't know what the problem is.

But after a short test i found a few things that doesn't work anymore.
Don't know if they are related to the fso-frameworkd patches or to the
new kernel.
Openmoko-panel-plugin doesn't start anymore with an error message [3].
The system time was set back to 1 Jan 2000. And the greatest problem i
had was wlan. I could access the eth0 device and it shows all available
wlan stations but i can't use my wpa2 protected wlan with wpa_supplicant
anymore. Iwconfig showed that i should be connected to my wlan but i
can't get an ip with dhcp anymore like with my old 2.6.24 kernel. The
dhcp client always tries and after 6-7 dhcpdiscover it exits with "no
dhcp server available".

That is the reason why i'm now back to the 2.6.24 kernel where these
things work. Maybe the userspace tools need a bit more tweaking before
they work together with the new 2.6.28 kernel. Or the configuration for
the 2.6.28 kernel have to be modified to work with my system. I removed
a few unneeded modules (i.e. Android things) and added a few modules but
i don't think that these have to do anything with my problems. :/

I attached my dmesg log. Maybe someone know of any other modifications i
can try to get the new kernel running a bit smoother. :)

Ciao,
