I believe this must be a separate driver. The two drivers would have
nothing in common except prologue registration stuff.

This would be unusually long name, that is

$ find . -iname '*openfirmware*' | wc -l
0

And in contrast:

drivers/video/offb.c
drivers/video/nvidia/nv_of.c
drivers/usb/host/ohci-ppc-of.c
drivers/usb/host/ehci-ppc-of.c
drivers/serial/of_serial.c
drivers/mtd/maps/physmap_of.c
...

So, I think we should stick with the "of" for consistency, while
confused users may consult with Kconfig for disambiguation.

But if you really want the expanded name.. just repeat it, and I'll
change the name.

Thanks,
