Oh, now I remember. This was the page0 breakage.

PSE gets disabled on the P4 due to processor bugs and hidden data
corruption and APM won't run without it. You might poke through the
archives on this.  It was a big PITA. :(

Your choices:
. Run with ACPI.  There's an apm compat interface if you have tools that
  depend on using the apm(8) command.
. Disable APM and ACPI.

APM is kinda useless on servers anyway so you aren't out a whole lot.
