Heh, you mean "here is the hardware information, please make a patch".
But your choice of red makes it truly a "bleeding edge" kernel :)
The fact that we have been using linux for ~ 10 yrs and nobody has
complained about the lack of this function yet says something...
Anyway, have a look at this and see if it is what you had in mind.
I figured it would be sensible to have a per VC colour, which is the
way I've done it. At end of 2.4.19pre5 patch is a $0.02 test program.
Paul.
