See attached file for complete lshw of the failed stretch upgrade

You need to do it again but without lshw outputting in xml format. With
no switches lshw outputs in plain text, exactly the right format for an
email attachment.

However:

'inxi -c0 -Gx' should be all we need to address this thread subject, as
would the lscpi or inxi commands suggested in a previous thread response.

The ProSavage8 S3 Graphics gfxchip described there, which has no KMS support and thus requires a user-space driver, fits into the following description from Stretch:

zcat /usr/share/doc/linux-image-amd64/NNEWS.Debian.gz:

linux-latest (76) unstable; urgency=medium

  * From Linux 4.8, several changes have been made in the kernel
    configuration to 'harden' the system, i.e. to mitigate security bugs.
    Some changes may cause legitimate applications to fail, and can be
    reverted by run-time configuration:
    - On most architectures, the /dev/mem device can no longer be used to
      access devices that also have a kernel driver.  This breaks dosemu
      and some old user-space graphics drivers.  To allow this, set the
      kernel parameter: iomem=relaxed

IOW, it is suggested that iomem=relaxed may need to be included on kernel cmdline for the old user-space xserver-xorg-video-savage driver to work with your gfxchip in Stretch.
