ok, ho settato il BIOS per dare l'interrupt alla scheda VGA.
adesso ho questo:
01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400

quindi, alla fine, mi viene assegnato IRQ 11, e lanciando X
ottengo messaggi positivi e rassicuranti:

quello che succede e` che non sembra esserci nessuna accelerazione
hardware, dato che tuxracer, gears, atlantis e compagnia bella
girano a un frame ogni quarto d'ora o giu` di li` :-((
dove sbaglio?
forse il DRI non c'entra niente?
come faccio a sapere se la scheda lavora come dovrebbe?
gia` che ci sono, posto anche il xf86conf...
