Thanks for your hints.
I made tests and it seems:
When you start startX (with a correct XF86Config file and a Atari monitor),
 it is not possible to change the resolution.
 The only way to change resolution, is to reboot (and under TOS to change resolution
 and then to run loadbsd.ttp)
With NetBSD on the console, iteconfig (options -w, -h and -d) does not seem to change 
resolution.
