description:
Pullup rev 1.7 (requested by mhitch in ticket #923)

The gcc3 compiler optimized away writing character data to the Cirrus chip,
which results in a blank display - making it rather difficult to do an
install or upgrade when using a Cirrus-based display.  Change the pointer
used to write the character and attribute to volatile.  The console screen
now shows data and is usable.
