I found the issue -- I was telling qemu to use the wrong kernel, it didn't have support for X32 compiled in. Oops! All is working now. Cheers, Brett -- Brett Neumeier (bneume...@gmail.com)

QEMU shouldn't need any special support for it to work in system mode at all. It's likely that something else is going wrong. thanks -- PMM
