I doubt the problem is specific to that code. Specifying the bus ID has
been necessary on many PPC systems for as long as I remember.

As a rule of thumb, I'd advise any non-i386 [1] user to run lspci|grep
VGA, and if that yields a single result, or it's obvious which one is
the card she wants to use, have her specify the bus ID. Don't forget to
mention that decimal/hexadecimal thingy. :)
[1] Assuming that primary adapter thing only works reliably on i386. I
can imagine it also does on alpha and maybe others, but I have no
experience on those.
