Interesting. The comments still indicate that kbd is the default vector.
In any case:
- just booted with a gentoo liveCD (3.3.0 kernel)
- tried the default reboot - hangs (last console message: "Remounting /
read only ..")
- tried with reboot=a - hangs (same last console message)
For what it's worth, creating a path for X86_64 mode to reboot through
the bios seems like
a good thing to put on the wish list.
