There _is_ a way to force a "default" mapping from userspace - haven't yet
tracked down how to do that though... ("default" as in only_one_in_use?)
You could try fooling with svgatextmode/setfont/alike ;)

Please DON'T default reset escape stuff to user editable maps...
resetting the console properly is hard enough even without that...
[imnsho the current state of the console driver is a bit broken as it
doesn't really do proper "hardware abstraction" ...]
FYI the current 2.1.xx vga.c has something like this:
/*
* The default font is kept in slot 0 and is never touched.
* A custom font is loaded in slot 2 (256 ch) or 2:3 (512 ch)
*/
if (set)
{
video_font_is_default = !arg;
font_select = arg ? (ch512 ? 0x0e : 0x0a) : 0x00;
}
if ( !video_font_is_default )
charmap += 4*cmapsz;
Hmm how to call "set_get_font(char * arg, int set, int ch512)" from
userspace with null arg? (setfont doesn't do that...)
