jQuery 1.3.2 works with Greasemonkey, 1.4.2 does not - the culprit is eventSupported function which is used only for some minor features, so we can just try{}catch{} around it.

I know it doesn't *solve* the problem, just works around it. I haven't been able to figure out how to make it work right (and there are probably far more numerous issues with Greasemonkey+jQuery integration, not just this one), but this patch works around the "Component is not available" exception, and now it's possible to use most of jQuery from within Greasemonkey scripts.

I don't think it would break anything. So by moving Greasemonkey from won't-even-compile to mostly-working it's a great progress anyway.
