It's not directly related, but there's similar output from "ifconfig"
that doesn't rely on the size of the dmesg buffer:

| $ ifconfig -a | \
|     perl -nlwe 'if (/^(\S+)/) { $cur_if = $1; } 
|                 if (/HWaddr ([0-9a-f:]+)/) { print "$cur_if: $1" }'
| eth0: 00:02:B3:11:55:40
| eth0:0: 00:02:B3:11:55:40
| eth0:1: 00:02:B3:11:55:40
| eth0:2: 00:02:B3:11:55:40
