I am afraid this will be a futile inquiry, but I still have to ask.
amd64 contains the 32 bit code with 64 bit extensions. This means that I should be able to run i386 programs, amd64 programs, and ia64 programs, right?
Following this thought process, it seems that I should also be able to run the official NVIDIA video driver on my amd64 system, even though the driver is currently only made for i386. However, I do not actually hold much hope for this being true due to the low-level nature of drivers. It would be all too convenient to be able to run the official NVIDIA driver on amd64.
Of course, when I just try to install the NVIDIA driver from ports I get the message that it was meant for i386. Providing it will not botch up my system too badly, I might just unmask it and see how it works.
Humph! I also just realized the the open source NVIDIA driver (nouveau) is not in ports (Unless they are under some odd name). I suppose I could try building it from source, though I do not hold a whole lot of hope in that working either.
