Log:
Final set of changes to make Alix1c work.
Fix IRQ tables (Thanks to Marc Jones)
Fix IRQ SLOT #
Comment out ram test in early startup.
make the debug print in lx/raminit.c a debug print, not emerg print
Set the default console log level to 3, but leave in the possibility of
running with more info (leave maximum at 11)
