Heh, well, most of the cue plugins in winamp are rather limited/buggy anyway, so whenever I want to play something with cues, I think foobar is generally the best bet. I do believe that zoom player has some support, but I forget how well it works. Foobar basically treats cues like you just opened a bunch of separate files, but most other players aren't quite so supportive of that system, and tend to do things a bit weirder.
I may yet make the switch, but old habits die hard, and I absolutely refuse to use WMP unless I absolutely need to (It eats up more processor time and RAM than winamp, and probably a good portion of other players as well).
Oh, and on the subject of processor time, is there any way I can speed up decoding H264 videos on here? My system tends to desynch on anything above 720p :/ I'd like to be able to watch those without large gaps of video dropped every so often due to the desynch.
The only other option for the Zero no Tsukaima release I'm watching is 704x400 Xvid, which looks a lot worse than the 720p H264 encode...
