I'm not 100% sure. Architecturally, they are errors on SPARC. Userspace
applications that do unaligned accesses are sent SIGBUS and usually killed.
For a driver, I would imagine that the kernel would catch this trap and
emulate or ignore it rather than go down in a blaze of glory. It should
generally be treated as an error, and every time I've seen the C code that
does it, it is usually straight forward to fix it.

I don't really know a whole lot about fbcon in general. I know that I
definitely get fbcon on the ATI chip (fb0), but I haven't really researched
how to get a console going on the NVidia one. I'd be happy to try it and
report results if you give me a bit of direction.
