I'm still not going to do the effort to implement that (which would require learning fbdev internals first), though. But while I dislike this feature, someone else might want it. The main problem here is that there are only 8 or 7 bits available for attributes, thus it's better to use them for something more useful. And here, fbcon already interprets this bit as bright background, thus this patchset makes vt use it instead of non-existant blink. There'll be more bits available once attributes get migrated into uniscr -- either 11 or 32 bits depending on chosen implementation. But I still wouldn't go too wild with them: the console is meant for recovery tasks as on any properly working system you can have an X terminal configured for pixel-to-pixel identical behaviour as anything console can do. Thus, only cheap improvements to attributes make sense. This patchset is currently at +3 net lines, this certainly counts as cheap. On the other hand, displaying the _glyph_ better would be worth some effort. Nicolas' uniscr that's already in Greg's tree did most of the work, what remains is a way to load and store a font with more glyphs (needs a sparse representation).
