The 24bit are not a problem as there is no such thing as "16bit" in an
encoded file. Internally, it's all floats (afaik) and it depends on the
decoder how much bits per sample there will be in the end. Peter's
Winamp plugin supports 16, 24 and 32bit output, for example.

The problem might be the 96kHz. None of the modes I know of are tuned
for that sample rate. On the other hand, you really don't need it. 96kHz
is designed for mixing and destructive editing of samples - it's needed
to keep a low signal to noise ratio when doing lots of alterations to
some sound. Since the average human can't percieve tones higher than
~20kHz, 44.1kHz are all you need. The 96kHz are useful if you mix and
master music - and that's not where Ogg is useful.

Besides, 96kHz encoded files would still be huge. If low-end soundcards
support that, it's more about baiting customers with buzzy features
they'll never need.
