OK, so I received my backlight from midi-rakete.de promptly, and installed it without any fuss. I tested it with my noisy inverter, and it worked.
Then I found this goldmine of a thread:

I would roughly estimate that the noise/whine from the inverter is 1/4 of the intensity of what it used to be, but it still irritates me.
Unfortunately I found that the backlight itself emitted noise. Guess I'll try to order a more silent one from saint_baz on Ebay.
