Je viens de passer sous GNU/Linux (Mandrake) un netpc Biostar IDEQ 200v équippé d'un chipset intégré VIA KM400 comme nombre d'autres PCs ou portables.
Par défaut, le pilote via n'est pas installé mais un pilote vesa peu efficace. Un site très utile pour fournir de quoi régler la difficulté se trouve ici:
http://unichrome.sourceforge.net/ Merci à son auteur.
Cela vous permettra de compiler un XFree 4.4 unichrome sans encombre:
http://sourceforge.net/projects/unichrome/
Ce dernier fonctionne effectivement. Et même si ce n'est pas un foudre de guerre, cela rend bien service en bureautique pour afficher tranquillement les hautes résolutions aux féquences choisies (alors qu'en vesa on dépasse péniblement 75 Hz).
Il vous faudra après avoir installé XFree 4.4 unichrome, modifier votre fichier /etc/X11/XF86Config-4
Voici celui que j'ai configuré pour le netpc Biostar:
