From http://www.openbsd.org/alpha.html in the "Project list" :
"Make X11 work on PCI VGA cards for machines without BWX"

Is anyone working on that, or does anyone know what is needed to do
that ?

BWX on alpha is Byte Word eXtension, which is if I remember correctly,
a set of 6 new instructions introduced with the EV56. Those instructions
enable the alpha to load/store data in 8 or 16 bits (before that, the
alpha could only load/store 32 or 64 bits at a time).

Cheers
