Lets > say I have an old 10Mbs ONLY card... are you declaring that it gets toasted > by auto-negotiate every single time? It's very simple. The devices at each end of a TP cable can autodetect speed. However, if the duplex mode is locked (set manually) at one end (whether it is locked at half or full duplex), you *cannot* depend on the other end to get the correct duplex mode. Sometimes it will work, sometimes it won't. Thus the advice to either use auto-negotiate everywhere, or use manual everywhere. One end auto-negotiate and one end manual is a recipe for disaster.
