Help with chroot on amd64/em64t

I work on a custom version of ubuntu, specially tailored for a computer
manufacturer, which distributes it with their systems. We distribute
about 1500 ubuntu copies/month.
It is mainly a rearragement of ubuntu live for i386, with some more
hardware supported and some changes on the packages provided.
One of the main difference is a working prototype of ubuntu-express, a
installer for ubuntu live.
Essentially, what this kind of installer does is
- it partitions the disk
- copies / from the cd to hard disk
- chroot to the recently copied filesystem, re-configures kernel, init
Up to now, all is well. The problem is that chroot does not behave
nicely on amd64/em64t systems.
When you copy everything to /, mounts /dev and /proc and chroots to it,
everything goes fine on i386.
But when the same is done on amd64 ubuntu, it fails miserably. It says:
chroot: Cannot run command `/bin/bash' : No such file or directory.
Gnu-coreutils-bugs mailing list is of no help. What happens is that the
exact same procedure works on
- warty i386 on several computers, including the ones which fail with
- breezy i386, same
- dapper (jan 4) i386, same
and does not work on
- breezy amd64 running on a amd64, a pentium4 em64, a celeron em64t and
a pentium d em64t
- dapper (jan 4), same.
I suspect there's something wrong with chroot on the amd64/em64t
Please, someone help me. I'm trying to get desperate on this :-)
