But NetBSD doesn't always use BWX on EV56, see sys/arch/alpha/pci/cia.c.
And xorg is using the sparce mapping for 8/16bits registers access on this
system, not the BWX instructions (I guess it's why the XFree86 has been
working on PWS500 for me as well; it's the same broken code in
XFree86 and xorg for the BWX case)

Maybe remote debugging will be enough (And I don't really have space for
more hardware :). I'll get back to you when I'll look at this.
