Couple of little things I noticed with a new RELENG_7 AMD64 box (as 
of yesterday)

ifstat from the ports cannot seem to find interfaces for some reason 
?  It works fine on i386

[ns8]# ifstat  -b
ifstat: no interfaces to monitor!
[ns8]#

[ns8]# ifconfig
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
         options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
         ether 00:15:17:50:40:28

snmpwalk -v1 -c xxxx ns8 .1.3.6.1.2.1.25.3.3.1  with ULE gives a bogus value

HOST-RESOURCES-MIB::hrProcessorFrwID.3 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.8 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorLoad.3 = INTEGER: 100
HOST-RESOURCES-MIB::hrProcessorLoad.8 = INTEGER: 100

vs using the BSD scheduler

HOST-RESOURCES-MIB::hrProcessorFrwID.3 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.8 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorLoad.3 = INTEGER: 0
HOST-RESOURCES-MIB::hrProcessorLoad.8 = INTEGER: 0
