Subject: Re: [PATCH] Add new framebuffer driver for Fujitsu MB862xx GDCs

From: Matteo Fortini <[email-masked]>
Date: Wed, 15 Oct 2008 15:40:15 +0200

What about the mb86290 framebuffer driver directly from Fujitsu which is 
in the mainline kernel?
It's from 2003 and supports only until 86293, but can it be used as a 
basis for a proper fb driver? It has a lot of features indeed...
