I did not know about -r, it was not mentioned in the tutorial I read...
How do I switch back and forth between different branches? I got a conflict
and could not switch back anymore. Then I deleted all files (except .git), I
should be able to get everything back with git checkout? Well, I didn't. git
newbie here...

I haven't used cowbuilder yet, for debian packages I us this, which I guess
is equivalent to your cowbuilder script:
DEB_HOST_ARCH=m68k debuild -B -am68k

Yes, but I am not trying to build a debian package, I try to build directly
from linux-m68k. This has worked, only the Amiga complained a missing
modules.dep (but I built in the network driver):

make ARCH=m68k CROSS_COMPILE=m68k-linux-gnu- 
make ARCH=m68k CROSS_COMPILE=m68k-linux-gnu- INSTALL_MOD_PATH=/data/m68k modules_install 

The kernel boots, it configures the network (static). When I try to ping a
host on my network, I get this oops(?).  A few seconds later I also get the
mismatch message I reported earlier (does not show up in dmesg?).

PS 2.6.28 did not boot: kernel too old. When was TLS introduced? I'll try to
apply the patch you mentioned in your other message.
