Hello,

I just uploaded some framebuffer stuff I found on the web in last months.
Check http://www.visuelle-maschinen.de/ctfb/fb

What I know about chipsfb:

There was a chipsfb which did not run on my i386 - ct65554 machine. I could 
not fix the problem also I did not understand anything about framebuffer 
drivers and the register set of the ct65554. So I decided to write my own 
driver. Of course I started with chipsfb, but most of it is gone and 
replaced. Time went by, i improved the driver and adapted it to the ct69000.
Than asiliantfb apeared on the sceene. Adrian Cox and I exchanged some mails 
with plans to merge both drivers - but, you know, we all have lots of other 
jobs and the project never starts.

From Mike McQuade <mi...@ci...>, I got mail (it is from 13. March 2001):

The ctfb verision 0.50 supports now 2.2 and 2.4 kernels. 
You can find it now under 

http://www.visuelle-maschinen.de/ctfb/fb/drivers/ctfb/

There is also asiliantfb and the old chipsfb available.

I did also some work on the video-in part of the ct69000 - yes I grabbed 
pictures. But it came not to a driver. Just a working userland application.
It is availiable under 

http://www.visuelle-maschinen.de/ctfb/fb/video_in_ct69000/

Actually I work with a i810 chipset and my current interest in ctfb is low.

I can not spent too much time in this but I can offer support and help and do 
also some testing, if nesesary. 

Sorry for the long mail.

Thomas
