You can find some specs here -

Audio Converters:
Dual AC-97 2.1 audio codecs with full-duplex capability, for simultaneous recording and playback at sampling rates up to 48kHz. Three stereo 18 bit A/D converters for high-resolution recording (provides 4x better resolution than 16 bit converters). Three stereo 20 bit D/A converters for high-resolution playback of up to 6 independent streams.


Based on this what bit-depth should I set in Fb2k (playing ripped wav files) ?
Can I set 20-bit fixed point padded to 24-bit ?
It uses a Cirrus Logic Crystal 4630 chip.

Probably 16 bit. Most likely the driver just trunicates everything above that anyway.

So when would it really use 18 bits for playback ?

Maybe if its doing any mixing or resampling onboard. Or it may just do everything at 16 bit anyway.
