AIUI the problem only crops up when i386 userland is used on an amd64 kernel. Perhaps I'm being hopelessly naive, but I'd hope that such a setup is not particularly commonplace.

FWIW, 64 bit kernel and 32 bit userspace is what I run on my notebook.

How do you set that up?

aptitude install linux-image-amd64
Actually, it might even be the default these days if you install the i686 version of Debian on a 64-bit machine.

I am running 64bit kernel with 32bit userland on a couple of my systems.
It's a very good option.

It's becoming the norm actually, lots of distro's do that by default or support it on their install/rescue media since it means they no longer need to build two separate userspaces, they just include two kernels to boot from on one disc, so for 99% of actual users there's only one specific disc image to download as a result.
Especially since a LOT of the time you _need_ a 32-bit userland to deal with a lot of binary packages out there or to get stuff running under WINE properly, it's easier for the "end user" images to stick to 32-bit userland even on 64-bit platforms. And even if you have a 64-bit userland you'll find it littered with various 32-bit-compat libraries.
Servers? Those are a different story, but many of those folks don't even need 32-bit compatibility so they can end up with a cruft-free pure-64-bit userland without all the 'compat' crap bolted in. So it reduces the size of the true-64-bit install media too, since there's no 32-bit cruft now.

IIRC that is what Linus recommends for many situations.
