Actually, the opposite is true. It looks like making PIO_CMAP
set the palette for all consoles was a feature that was
written in.
>Is this same for 2.1.x?
Yes, but I have a feeling it shouldn't even be in console.c
where it is. It probably should be part of the new video
stuff. But this was changing at an alarming pace, so perhaps
it will be soon.

It would be easier to change set_get_cmap(unsigned char *arg, int set)
to set_get_cmap(unsigned char *arg, int flags, int cons) and allow
it to either set all palettes or a specific one. This should be
moved to the video drivers though, IMHO.

It is clumsy, but not hard at all to do, using VT_RELDISP and
all that stuff.
