98d83734f4 this is a full fix for writes not aligned to the sample size selected.
should be a no-op in most cases.

62c631ed7f * Ignore the wierd fakechan workarounds for simplex in dsp_ioctl().
Without this, ioctl commands for setting formats and speeds were
  essentially ignored for simplex devices until the application actually
  performed a read or write.
* Make sure that both channels are set in the SB mixer code and provide a
  mixer table specifically for the ess18xx which supports the extended
  accuracy available on this part.
* Fix a stupid bug in ess_format() which ignored the passed-in format and
  changed the hardware based on the value which was set last time. This
  meant that the hardware setting was often not set correctly at all.
* Add a custom identify driver for the ESS1888 which automagically detects
  and adds the device in a pseudo-PnP way. This driver also emits the magic
  sequence which enables the sound hardware after a hard reset, allowing
  it to work correctly for the sound hardware of a PWS 433au (and probably
  all other PWS class alpha machines).

With these changes, I was able to play back simple sounds on my 433au. I
have not tested recording or any other formats other than 8bit ulaw and
16bit stereo.

5b78a73443 * add a non-reset device- will not reset the channel on open. you
will have to mknod yourself for now.
* don't eat the first write()
* partial rvplayer fix- don't panic on unaligned writes unless our
  feeder chain requires them for downconversion.  a fuller fix is
  on the way.

d6a0e38a1b Remove five now unused fields from struct cdevsw. They should never
have been there in the first place.  A GENERIC kernel shrinks almost 1k.

Add a slightly different safetybelt under nostop for tty drivers.

Add some missing FreeBSD tags

987e59726a say hello to newpcm. it is not yet enabled, requiring new pnp code from dfr
to compile successfully.  further details will be provided in the commit
enabling newpcm.
