RE: HP Jornada 690 bright/contrast problems

So I will have to modify kernel sources if I want to see something in the 
console, right?

I'll search in the list, I think I read the name of the file to modify 

Thanks for all!

So I had a look, and the problem is that wscons ioctl's only let you
chnage the colormap for the indexed case (i.e. depth <= 8).

The semantic gap is that rasops internally maintains a mini 16 entry
colormap for its internal operation (even for larger depths).  For the
indexed case, it's just the indexes, so when you change the device
colormap (with wscons ioctls), display changes accordingly.  For
larger depth the colormap entries of internal rasops colormap are the
actual RGB values, but there's no interface to change the rasops
