Anyway, after 'kldload snd_uaudio' the keyboard gets claimed:
(from /var/log/messages):
Feb 20 20:10:35 kg-v7 root: Unknown USB device: vendor 0x0a4d product 0x00d2 bus \
                uhub2
Feb 20 20:10:35 kg-v7 kernel: ugen0.3: <Evolution Electronics Ltd.> at usbus0
Feb 20 20:10:35 kg-v7 kernel: uaudio0: <Evolution Electronics Ltd. USB MIDI keyboard, \
                class 0/0, rev 1.00/2.52, addr 3> on usbus0
Feb 20 20:10:35 kg-v7 kernel: uaudio0: No playback!
Feb 20 20:10:35 kg-v7 kernel: uaudio0: No recording!
Feb 20 20:10:35 kg-v7 kernel: uaudio0: MIDI sequencer
Feb 20 20:10:35 kg-v7 kernel: pcm6: <USB audio> on uaudio0

Sorry about the brainfart.
