You can tell it was a few years ago and I don't have the datasheet at  
hand right now ;)
If you want the datasheets I used ( downloaded from Analog Devices  
when they still made the chips ) I'll mail them to you.

True. adtxxxx? ;)

I think there are examples in the code where drivers have names just  
as close to trademarks as this one, think radeonfb, voodoofb,  
unichromefb, xboxfb. On the other hand the companies who own the  
trademarks are probably not aware of our existence.
We should probably take care to use the right capitalization in  
manpages as a matter of courtesy but IANAL.

have fun
