User-agent: Mutt/1.4.1i

The following patch series complements "Partial IDE DVD emulation" which was
added in revision 1.66 of ide.c and that was generating the following timeouts
for OpenSolaris guests when trying to access the ATAPI CD-ROM (during 
installation for example):

  WARNING: /address@hidden,0/address@hidden,1/address@hidden (ata1);
          timeout: abort request, target=0 lun=0
  WARNING: /address@hidden,0/address@hidden,1/address@hidden (ata1):
          timeout: abort device, target=0 lun=0
  WARNING: /address@hidden,0/address@hidden,1/address@hidden (ata1):
          timeout: reset target, target=0 lun=0
  WARNING: /address@hidden,0/address@hidden,1/address@hidden (ata1):
          timeout: reset bus, target=0 lun=0

It has been tested to fix the problem and not to introduce any regression 
with several releases of Linux, BSD (FreeBSD, OpenBSD, NetBSD and
DragonflyBSD), Windows 2K and OpenSolaris (Nexenta, Indiana, SXDE) and Solaris
10 guests in x86 (32bit) and amd64 (64bit) hosts and to match exact responses
when compared to responses received by physical SATA and ATAPI DVD-ROM devices.

  Patch 1/2: fixes GET_CONFIGURATION to allow OpenSolaris CD-ROM access
  Patch 2/2: uses DVD-ROM as model name for INQUIRY and IDENTIFY DEVICE
