I tried SSX3 over lunch. As you said, it clearly runs in 512x512. Enabling progressive scan produces an image no different from that of the PS2, however (expected, as the PS3 is no longer de-interlacing the image). I also tested Silent Hill 2 and Tekken Tag.
Silent Hill was also known for using a different resolution and the results are every bit as terrible as those Square-Enix logos floating around. Tekken wasn't nearly as bad as expected, however. A bit flickery, but overall clean enough.
That just confirms what I've said in the original post.
Horizontally misaligned pixels (like the Squenix logo) happen when title output an odd horizontal resolution (eg. 512). Tekken (as most early titles) was using full 640, so it will not be affected.
Progressive scan "fixes" things because titles change their Output buffer to 640 (so in case of SSX and others like it, title renders 512x512, then scales contents to 640x480. When the same title runs interlaced, 512x512 is copied to 512x512 and CRT handles the "scaling").
The issue is not in deinterlacing per se - it's scaling of the 512 signal to fit 640.
This is also why ICO works (640x240), while SOTC has problems (512x512, except when running progressive).

Anyway ... I do wonder if there are any progressive games that use non-standard output resolutions?
No, if you tried outputting progressive in non-standard res, it would just get displayed in a smaller window (which wouldn't pass Sony Q&A). See above how games handled this.
are we sure the PS2 even scaled the images at all
It's "scaling" by outputting a different H frequency (as you noted yourself). So pixel just becomes stretched on the CRT display.
But this only worked for interlaced outputs - PS2 CRT wouldn't allow this on progressive (so we would scale the buffer before outputting it in that case).

a combination of non-standard buffers and deinterlacing algorithm, may be something like this?
Well, it appears (on PS3 at least) to be horizontal scaling problem, but yea, it's clearly a problem of how scaler works. My Samsung LCD doesn't do this, so I can't say if TV has the symptoms with same titles.

Well software emulation hasn't exactly done wonders for Xbox 360 backwards compatibility...
Afaik software emulation on PS3 is already better then 360 ever was, whether it'll ever be 97+% I wouldn't know though.
