Not as a skeleton from which you can build up a new driver ?

Ok i will look at the 3Dfx driver.

BTW, the main difference i see between skeletonfb and the other driver
is about the _init function. if contains lot of stuff to initialize the
fb_info structure and such.

But when i look at the neofb for example, but it is the same in
matroxfb, i see that pci_register_driver is called with a structure
containing the neofb_probe function, which is something absolutely not
present in the skeletonfb.

Too bad, ...

I would have been nice to have such a thing before you remove the
backward compatibility from the new kernels.

Anyway, thanks for your help, i will look at the existing drivers then.
