Вот завалялось, для 2.x.x сам докрутишь. :)
Hello! There is a linux-2.0.18 console patch for displaying AltGr
keyboard state as console color border (an additional led). You can swap
scroll lock and AltGr leds. This is useful for Cyrillic, Greek and
others, who use AltGr keyboard lock state to enter chars from 128..255
range.
Regards,
Sergey Ya. Korshunoff p5.f434.n5020.z2.fidonet.org
PS: Thanks Vladimir Goncharov and Seva Semenov for support.
