It's a kernel/loader issue, mostly. The stack layout is very different in 64
bit mode than in 32 bit mode (or so I gather from messages from DAvid &
James). This means that when running 32 bit apps, the stack needs to be
treated differently, and the kernel doesn't do that right (yet).

Well, i386 will work. amd64 YMMV.

It's been said several times on this list that running an amd64 as an i386
works quite well and _is_ really fast. I can't confirm that, though.

worked.
