It's worth noting that the reason legacy emulation causes problems
is often that FreeBSD has not undone the BIOS's configuration of
the EHCI controller. Adding 'device ehci' to the kernel config seems
to fix this in many cases. What hardware were you seeing the problem
on, and does it have an EHCI controller that's not being set up by
FreeBSD?

Many PCs these days have no PS/2 mouse or keyboard ports, so it's
important that we work with legacy emulation turned on where possible.
