Ethtool is a newer program and not many ethernet drivers support it,
especially systems one running 2.4.17 or older, or a 2.2.x or older,

For the older system you would need mii-tool.

Could be.  Under RH 7.2 you could put that line in /etc/rc.modules and
hope it doesn't screw with kudzu.

You'd be better off putting

ethtool -s <interface> speed 10 duplex full

in /etc/rc.local
