This bug (activating show_mem) can be reproduced without the dd on
tmpfs. From a initial ramdisk containing only a shell, some libraries
and the following init script:
: #!/bin/sh
: echo Loading....
: sleep 60
Pressing shift+scroll lock during the sleep generates an oops at the
beginning of the show_mem function also. The issue does thereby not seem
to be related to any of the kernel code compiled as modules. It pretty
much rules out tmpfs itself.

The kernel has been run on multiple hardware (similar (not fully
identical) type though) and memtest86+ has been run for several hours
without any trouble.

Can't be fully ruled out indeed, since during memtest86+ no kernel with
ACPI loaded has been loaded the BIOS may very well be less active or be
inactive. And thus not showing any memory changes caused by BIOS RAM usage.
