vmware's virtual implementation of acpi collides with freebsd. best
practice is to disable acpi altogether in the actual config file on
the host o/s for the VM by manually placing:
acpi.present = "false"
monitor_control.disable_apic = "TRUE"
in the whatever.vmx config file, and restarting the virtual machine.
read up on the vmware forums for some more information from yours
truly on trying to beat freebsd into running on ESX. there's
additional problems you'll run into w/r/t crappy smbfs performance,
agent support, and some esoteric problems like nanosleep() calls
eating CPU instead of actually idling.
