Nope. No luck. I get this issue:
    http://tinyurl.com/5dhtl

Hissing, volume buttons work, both from amixer and from headset's volume
buttons, but no audio. When I try to send audio, I get this:

[21:35]jesse@trevarthan:[~]% aplay -B 1000000 -D plughw:Headset /usr/home/jesse/.kde3.3/share/sounds/maximize.wav
Playing WAVE '/usr/home/jesse/.kde3.3/share/sounds/maximize.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono
ALSA lib pcm_hw.c:592:(snd_pcm_hw_drain) SNDRV_PCM_IOCTL_DRAIN failed: Input/output error

In addition, if I disconnect the headset by pushing the function button, the
hissing stops, and I get confirmation that the SCO connection has been dropped:

[22:07]jesse@trevarthan:[~]% btsco 00:0D:44:36:E6:F4
Device is 0:0
Voice setting: 0x0060
RFCOMM channel 1 connected
recieved AT+CKPD=200
opened hwdep
connected SCO channel
Setting sco fd
Done setting sco fd
recieved AT+VGS=13
Sending up speaker change 13
recieved AT+CKPD=200
disconnected SCO channel

Pressing the connect button on the headset after this yields
this output:

recieved AT+CKPD=200
opened hwdep

But then it hangs and I have to physically remove the dongle
from the USB port and replug it to get things working again.

I'm using a patched (mh3) Gentoo 2.6.10-r6 kernel. Everything
but the VERSION hunk applied successfully.

Is this an irreparable incompatibility with the Silicon Wave
chipset? I'm willing to do any debugging and/or patching
necessary, but my guess is that Marcel already has plenty of
these chipsets laying around.

If there's no hope, can anyone recommend a USB BT 1.2 dongle,
hopefully with flash upgradeable firmware, that works well
with Bluez in headset and handsfree profile modes?

Thanks!
