What version are you using? In -current (and should be in 1.5), that line
is "#if !defined(__i386__) && !defined(__arm32__) && !defined(IPL_AUDIO)"

That's not the way to do it. That structure needs to be filled in, not
just declared. It is filled in when you configure audio into your kernel.

Yes! Here are the dmesg lines from my card:

eap0 at pci0 dev 14 function 0: Ensoniq CT5880 CT5880C (rev. 0x02)
eap0: interrupting at irq 24
eap0: SigmaTel STAC9721 codec; 18 bit DAC, 18 bit ADC, Rockwell 3D
audio0 at eap0: full duplex, mmap, independent
midi0 at eap0: AudioPCI MIDI UART

The -current GENERIC kernel should contain everything needed to make this
work.

Take care,
