The squashfs image is stored inside the ISO9660 container as 
"sidux/sidux.686", it is bootable and the installed kernel (2.6.29-rc7-git3
+ aufs2, it's required for the live system, but I have checked that it is 
also reproducable with plain linux-2.6.git and without any patches, outside
of a live environment) exposes this problem.

Sources for all software installed inside the squashfs image is available 
at:
	http://sidux.com/slh/squashfs/sidux-snapshot-minimal-i386-200903101824-source/

The (Debian-) packaged kernel source as:

and as plain tarball with all patches pre-applied:
	http://sidux.com/slh/squashfs/linux-source-sidux-2.6.29-rc7.tar.bz2 [51 MB]

which consists of the following sources/ patches:

Thank you a lot for your efforts, I'm now going to test Geert 
Uytterhoeven's proposed patch and will report back.
