How to display 256 colors on the vga console shell ?

[Olivier Cochard-Labbé]

Hi,

I'm trying to display 256 colors on my vga console but didn't reach to
display more than 16 colors.
I'm using this perl script for my test:

I'm using -current (r253755) with the default xterm for all ttyv.
I've tried different vidcontrol mode (MODE_280, MODE 279, MODE_261)
but still 16 colors for each try.
The splash screen and the screen saver (rain_saver.ko) are able to
display more than 16 colors on my laptop but why not the console ?

Thanks,

Olivier
