That patch was rought draft for feedback. I applied your comments. This 
patch actually works. It includes my backlight fix as well.

Glad to hear it.  I had to make the following changes
in order for it to build.
However, I still have build errors for aty.

Ug. I see another problem. I had backlight completly compiled as a 
module! Thus it hid these compile errors. So we need also a 
CONFIG_BACKLIGHT_CLASS_DEVICE_MODULE check as well. Can sysfs handle this 
well or would it be better the the backlight class be a boolean instead?

SCSI works as a module and it uses sysfs.
See drivers/scsi/scsi_sysfs.c.
Does that answer your question?  I wasn't quite sure what
the question was.

I'm scratching my head on how to configure a modular driver and 
two modular sysfs classes. 
 

Next question, based on:
drivers/built-in.o: In function `probe_edid':
(.text.probe_edid+0x42): undefined reference to `fb_edid_to_monspecs'

Should backlight and/or display support depend on
CONFIG_FB?  Right now they don't, so the above can happen...

I already sent a patch to Andrew to make backlight/lcd work independent of
CONFIG_FB. Display is still in the alpha stage. In time it will work 
independent of CONFIG_FB.
