If I did this right, it doesn't help. I built in the vesafb as well as your 
new nvidafb, then booted with the commandline

 vga=0x31b video=nvidiafb:1280x1024-32@60

It looks like the nvidafb got the first bite of the cherry:

 ...
 nvidiafb: CRTC 1 is currently programmed for DFP
 nvidiafb: Using DFP on CRTC 1
 Panel size is 1024 x 768
 nvidiafb: MTRR set to ON
 Console: switching to colour frame buffer device 128x48
 nvidiafb: PCI nVidia NV25 framebuffer (128MB @ 0xE0000000)
 vesafb: probe of vesafb0 failed with error -6
 ...


Do you know if the nvidia developers lurk on lkml? I seem to remember somebody 
saying that they do. If so, is it worth asking them for a bit of help with 
this? I know they're not about to open source their binary driver due to ip 
license problems, but the information we require to overcome this problem in 
the fb driver is probably quite trivial in nature. I assume they have been 
forthcoming in the past wrt the open source X driver.

What do you think? Worth asking?
