Voice modems will be a hard find. And many of those pre-dated v.92.
Back when I was on dialup, I had decent luck with lucent cards. Although still win-modems and needed drivers / firmware. I had a USR card that was nice, but 3com bought them out and the firmware I upgraded with during that transition bricked my card.
I'm not a fan of linuxant, I'm glad it's an option. But their function is to provide what the manufacturer "should have" provided. A driver for hardware. So I try to avoid connexant hardware so I can avoid linuxant. There's just something about having to buy your hardware twice that irks me.
There's probably a few lists, but you'll need to know the chipset in a lot of cases.
Or run down to a goodwill tech center and grab a dozen different cards and try them.
