- update to 20061031 cvs snapshot (now uses aio and supports acpi and a new

  qcow2 image format)
- properly respect NOPORTDOCS
- make -serial /dev/cuadX work (modified patch from this post:
  http://lists.gnu.org/archive/html/qemu-devel/2006-09/msg00201.html , and hi
  Michael! :)
- add WITHOUT_SDL (hi joshe! :) and WITHOUT_CDROM_DMA knobs (the latter to work
  around atapicam problems in FreeBSD guests with the now by default enabled
  ide cdrom dma patch)
- use OPTIONS

 (the rtl8139c+ that model=rtl8139 emulates needs less cpu than qemu's
 default ne2k nic which is driven by ed(4), it has not been made default
 only because it may not work with all guests yet.)
+- qemu now uses aio at least for ide dma, so if you get `Bad system call'
+crashes that is because aio is not (kld)loaded.
+- if you get repeated `atapi_poll called!' console messages with FreeBSD
+guests or other weird cdrom problems then thats probably because the guest
+has atapicam loaded, which for reasons still to be determined has problems
+with qemu's now by default enabled cdrom dma.  You can build the port with
+CDROM_DMA disabled to disable it.
+- if you build qemu wihout SDL and then get crashes running it try passing
+it -nographic.  This should probably be default in that case...

 (the rtl8139c+ that model=rtl8139 emulates needs less cpu than qemu's
 default ne2k nic which is driven by ed(4), it has not been made default
 only because it may not work with all guests yet.)
+- qemu now uses aio at least for ide dma, so if you get `Bad system call'
+crashes that is because aio is not (kld)loaded.
+- if you get repeated `atapi_poll called!' console messages with FreeBSD
+guests or other weird cdrom problems then thats probably because the guest
+has atapicam loaded, which for reasons still to be determined has problems
+with qemu's now by default enabled cdrom dma.  You can build the port with
+CDROM_DMA disabled to disable it.
+- if you build qemu wihout SDL and then get crashes running it try passing
+it -nographic.  This should probably be default in that case...
