This alarmed me; I don't want to see VIAs problem become a DRM wide 
rule.

But it seems as if this alignment is enforced only through the device 
specific code (xxx_mm.c), and that there really is nothing to worry 
about.

Has me wondering though; Why does sis_mm.c enforce the same alignment? 
Is this just a safe value? Why does this need to be overridden? Do some 
engines on some sis hardware require wider alignment, while normal 
alignment needs to be 16 bytes?

Anyway, that's driver specific, not set in stone. Nice work,

Luc Verhaegen.
