syntax for "minor triad sus 2"

[Kieren MacMillan]

[Lilypond 2.11.33-1]

Hello all,

I can't seem to get a simple minor chord sus 2 in \chordmode...  =\

This (which was my intuition, and the docs imply)

    bandChords = \chordmode { gs2:m.2/ds cs:maj/ds }

throws an error. My "fix"

    bandChords = \chordmode { gs2:m3.2/ds cs:maj/ds }

doesn't throw an error, but the output is "G#/sus2/addb3/D#" instead  
of the desired "G#m sus2/D#".

Any help would be appreciated.
Kieren.
