o.k., here is the story:
we are developping a uwb (ultra wide band) network chip.
this should be a wireless 100-500 Mbps with Qos communication chip. ( bluetooth and WiFi, beware ;-)
the prototype i am working on has it's registers and rams mapped as memory on a PCI card.
i tried using /dev/mem to access it, but it didn't work.
so i tried looking at examples and builded my own driver.
The new way of doing it from userspace is by mmapping /proc/bus/pci/XX/YY AFAIK, but /dev/mem works for me. You must be doing something wrong.
