I updated -current to r265915 w/ amd64 kernel and I get a panic
when I startx instantly (no video output of panic).   There is a LOR
right before the panic.

This is built using the VT kernel definition.

loading the old kernel built _at_ r264316 continues to load fine.

here's what normal under the old kernel looks like
