In 0.0.9, no, it can't be done. However, the EvStack code
(to be integrated into the next major GGI release) _is_
just a simple config option. Now that Linux has the
CONFIG_VT config, when CONFIG_GGI is enabled it activates some
key #ifdefs in drivers/char/*.c and drivers/char/Makefile,
disabling the current console code. 90% of this has already
been `found' for us by CONFIG_VT #ifdefs.

All the Kernel code in the EvStack release (see http://salsa.visus.com/~jmcc
for browseable source code) is in the drivers/console/ hierarchy, save
for a lonely ascii.h in include/linux, and the include/ggi/ tree. If
CONFIG_GGI is enabled, drivers/console/Config.in `lights up' and the
GGI portion can then be configured.
