A combined 32/64 grml CD would be nice, like http://www.finnix.org/blog/wp-content/uploads/2008/06/finnix_dev_boot_menu1....

This distro is equivalent to grml-small or grml-medium. I use it for PowerPC admin (32 and 64).

Grml CD has previously included two versions of Python, for example. Size-wise, two kernels is not a big deal.
