This is a problem. You're already using the /mnt mount point for
something else. I would suggest making multiple directories under
/mnt before you start mounting anything (in step 1) and then use them
for separate things. Also, typically you don't want to use /media
yourself; the freedesktop.org stuff uses that automatically for other
mount /dev/sr0 /mnt/disc
mount -o loop /mnt/disc/LiveOS/squashfs.img /mnt/squash
mount /mnt/squash/ext3fs.img /mnt/img
rpm -r /mnt/img -qa

It's a db4 type database that stores RPM data, not packages
themselves. You can query it using the '-r' switch. By default, an
'rpm' command will use the RPM database of the system you're
running. To have it use an alternate location, use '-r' to point to
the place *under which* the /var/lib/rpm directory lies:
rpm -r /mnt/img -q glibc

Hitting e.g. the Esc key works for me.

Kernel mode setting at work. I believe there are kernel parameters to
effect a change in the default resolution, which is otherwise set by
the kernel to be "as high as I can successfully manage." As a result,
fonts on the text terminals can be small for some people. (Me too,
