Unfortunately neither

It seems there is a new kernel boot option "vdso32" which is used
to control
the behaviour of vdso for 32-bit programs (such as scratchbox)
running under
64-bit kernels. There is no /proc file to control this, however.
Please change the scratchbox documentation, and the message
displayed when
scratchbox detects the bad vdso setting, to mention that if a 64-
bit kernel
is in use, the (only) way to fix the problem is to set the vdso32=0
boot
command line option.

You could document this yourself in the wiki. The front page of this
is at http://www.scratchbox.org/wiki/Scratchbox.
If you understand the cause of the issue, an explanation would be
appreciated by those who do not.
