to add to the file /etc/network/interfaces
\r
in the section where you specify the settings of the network card option hwaddress
auto eth0
iface eth0 inet dhcp
hwaddress ether 01:02:03:04:05:06

TO puzzled.
MAC flashed to the card itself, i.e., its change is possible only in the context of specific settings, a working OS. Statement of the problem "forever change" is incorrect.
The maximum that can be changed on the OS level to indicate that it needs for the interface use a different MAC. And here "the script in the startup" is no worse than any other way.

two options:
\r
1)in NetworkManager in the properties for the wired interface in the column mac address
2)in the /etc/network/interfaces to have the interface to set the option hwaddress
for examples see man interfaces.
\r
auto eth1
iface eth1 inet static
address 192.168.1.200
netmask 255.255.255.0
hwaddress 11:22:33:44:55:66

Using hwaddress in /etc/network/interfaces, you cannot change the Mac address of the card. This option is there for.

I'm not good at ubuntu. But something tells me that in /etc/udev/rules.d/ there is a file persistent-net.rules
Him and rule.

In Ubuntu 10.10, the Network Manager settings wired interface bar appear "Cloned MAC address", to set there the new MAC address of the network interface.
Try.
