Hi,
the following patch (against 2.6.5-rc2) teaches fb to use class_simple.
With this patch udev will automagically create device nodes for each
framebuffer registered. Once all drivers are converted to
framebuffer_{alloc,release} we can switch to our own class.

yeah, it's about time!  Didn't I post this patch a few months ago... :)

Hum, I remeber your patch that did the same thing, but it didn't use
class_simple, did it?

I think I had one version that did, but who cares, it doesn't really
matter :)

notebook:~# tree /sys/class/graphics/
/sys/class/graphics/

"graphics"?  Why that?  Why not "fb"?

It doesn't really matter to me, just curious.

It was discussed a while ago (this is James):

I'd rather use "display" here. "video" is too broad and will cause
confusion with multimedia stuff.

Exactly my comment. I was thinking about `graphics' instead of
`video', but indeed `display' sounds better. Gr{oetje,eeting}s,

I prefere graphics myself. Display sounds to generic. That is what video
and graphics output is piped to. Since fbdev doesn't handle video ouput
normally this is kind of fuzzy sounding.

Well, /sys/class/video is already taken by the V4L core code, so if
"graphics" doesn't confuse people, it's ok with me.

thanks,
