just add one of this options to make our linux screen console to have bigger than old time standard 80x25 mode.
ie : kernel /vmlinuz-xxxx ro root=/dev/xxx rhgb quiet vga=VVV
where VVV is one of this number 791 is sufficient enough for me.
791 - 1024x768, 16 bit
792 - 1024x768, 24 bit
794 - 1280x1024, 16 bit
795 - 1280x1024, 24 bit
reboot the machine for setting to be applied.
