If you try to set the default console fonts on SSH or from local xterm, you
# consolechars -d
set_kernel_font: Invalid argument
On console this seems to work fine. /etc/sysconfig/i18n:
This happens with RHL 6.2 too, at least.
This is intentional - setting different characters from anything but the console
doesn't make sense.
Also, adding this would be impossible - You can't use ioctl() on devices that
are used by someone else.
