The 3.0 sources have references to a rotation direction setting (clockwise or anticlockwise). It's documented in sysd/data/ereader.schema, see below. But of course, it's possible that this may just be a holdover from the DR1000, and not actually implemented in the DR800.

But it might be worth trying to set it to clockwise (the code says that the default is anticlockwise), then maybe rebooting after a change to the dr.ini file?
/apps/er/sys/display/rotation=clockwise

    <schema>
        <applyto>/apps/er/sys/display/rotation</applyto>
        <key>/schemas/apps/er/sys/display/rotation</key>
        <owner>sysd</owner>
        <type>string</type>
        <default>anticlockwise</default>
        <locale name="C">
            <short>Rotation direction, clockwise or anticlockwise</short>
            <long></long>
        </locale>
    </schema>

It seems that you can also change the standby timeout in the dr.ini file (it's 30 minutes by default).
Please note that I don't have a DR800 and I've never tested this!

    <schema>
        <applyto>/apps/er/sys/power/min_standby</applyto>
        <key>/schemas/apps/er/sys/power/min_standby</key>
        <owner>sysd</owner>
        <type>int</type>
        <default>30</default>
        <locale name="C">
            <short>Idle time in minutes before standby, -1 to disable</short>
            <long></long>
        </locale>
    </schema>
