5 * this really is an extension of the vc_cons structure in console.c, but
6 * with information needed by the vt package

16 * Presently, a lot of graphics programs do not restore the contents of
17 * the higher font pages. Defining this flag will avoid use of them, but
18 * will lose support for PIO_FONTRESET. Note that many font operations are
19 * not likely to work with these programs anyway; they need to be
20 * fixed. The linux/Documentation directory includes a code snippet
21 * to save and restore the text font.
