I tried using the 32 bit version instead, and it worked great. Moving projects over from the yum distro to the WINE version went much smoother than I had expected, and Synth1 loads with no complaining.
So for anyone who happens to have this problem: If you have Fedora (or some other hard-to-work-with flavor of Linux) and you're trying to make VSTs work with the apt-get/yum/dnf distro of LMMS, here's your answer:
You can't. Use WINE instead, and download the 64bit or 32bit versions of LMMS, depending on your WINE build.
However, there's still one problem for me: The VSTi window isn't working.

The normal display flashes for a fraction of a second when I open the window, then it changes to whatever was behind it when it opened. Only individual components of the regular display show up, and that's only when they change (like if I moved my mouse over a control and it highlighted itself, that control would show up)
The main problem has been solved, and this new problem will probably prove to be nothing more than a minor annoyance, but any help you can offer would be appreciated.
Update on new problem: I ran LMMS in terminal, and I discovered that every time that I move my mouse over the VSTi window, the debug is flooded with this one line:
I don't know if this is relevant, I guess it might be time to get a new graphics driver lol
