As Blair said, 64bit binaries needs to be in `/emul/linux' subtree,
and 32bit in `/emul/linux32'.

I did not see anything obvious with your trace. Can you try to modify
emul.linux.kern.osrelease to emulate a 2.6 Linux kernel ?

njoly@lanfeust [~]> sysctl emul
emul.linux.kern.ostype = Linux
emul.linux.kern.osrelease = 2.6.22
emul.linux.kern.osversion = #0 Wed Feb 20 20:00:02 CET 2002
emul.linux32.kern.ostype = Linux
emul.linux32.kern.osrelease = 2.4.18
emul.linux32.kern.osversion = #0 Wed Feb 20 20:00:02 CET 2002

The main idea was to create suse100-32 compat packages by using most
of the current suse100 infrastructure. I thought that simply including
the suse100 Makefile would do most of the trick, but we need to
redefine some variables such as SUSE_ARCH, MACHINE_ARCH, EMULSUBDIR,
etc...

I'll try to set up a message about this to tech-pkg@ later today.
