I very much doubt this for several reasons. Consider also this (on RH 6.1+2.2.14):

iapetus ~# arp -a
iapetus ~# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:50:04:21:99:04
          inet addr:192.168.0.39 Bcast:192.168.0.255 Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          Interrupt:10 Base address:0x300

iapetus ~# arp -s 192.168.0.111 11:22:33:44:55:66
iapetus ~# cat /proc/net/arp
IP address HW type Flags HW address Mask Device
192.168.0.111 0x1 0x6 11:22:33:44:55:66 * eth0
iapetus ~# arp -a
? (192.168.0.111) at 11:22:33:44:55:66 [ether] PERM on eth0
