All but EH[sblock]Gansk is correct about the 3.5 FAQ. On page 60, someone asks about golems immunity to magic. The first paragraph of the reply is as follows: "As noted in each golem's entry, a golem resists any spell or spell-like ability that allows spell resistance. (In previous versions of the D&D game, golems were impervious to most supernatural effects as well, but that is no longer the case.) In most cases, you can tell if a spell or spell-like ability works on a golem by simply looking up its spell resistance entry. Let's take a quick look at the effects you've listed:..."
It goes on to cite examples of various spells.
The Fiend Folio was published in the transitional stage between 3.0 and 3.5, so I have treated what it has said about supernatural effects and magic immunity as an error. I have just read the SRD about golem immunity to magic, which does with the 3.5 Monster Manual at the beginning of the general golem entry, but every individual golem makes no mention of supernatural effects in its entry. Taking that with the 3.5 FAQ, it seems that there was a cut and paste error from 3.0, so I will keep the ruling that golems are not immune to supernatural effects.[/sblock]
