-current doesn't boot on xen

[coypu%sdf.org@localhost]

Hi all,

I tried installing -current in prgmr.com, it panics at boot.
Note that this setup was able to boot 8.2 and -current doesn't boot at all.
The change seems to be from http://gnats.netbsd.org/55207

I think the current code is less functional than it was before.
