kexec or similar for FreeBSD

So it has been a while and a lot of hair pulling but
kload is sorta alive and kicking.
It can now load the kernel from userspace, copy it over the running
kernel and jump the the kernel entry point.

I'm still having problems getting through the boot process due
to interrupts arriving for unconfigured handlers.
Fatal Trap (30)

If anybody has some experience with acpi and interrupt configuration in
general and is willing to help please let me know.
