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. > If someone knows what's really going on and how to better word this > template, please, please let me know. > > I'm not sure, but I think you probably need the BusID unless you're > using the fbdev driver. 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. -- Earthling Michel Dänzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast
