[Voyage-linux] Howto get Framebuffer working

[Kim-man 'Punky' TSE]

Hi all,

There had been reported problem on the framebuffer support in voyage.  
But I am quite suere lxfb.ko should be included in 0.5.2 and lenny release.

You may find the documentation of lxfb in the link below
    http://lxr.linux.no/linux+v2.6.26.7/Documentation/fb/lxfb.txt

You can also run "modinfo lxfb" to see the support module parameters. 

If anyone in the list has successful story in using the framebuffer or X 
with ALIX, please share your experience with us.  Of course, I would 
want to get the framebuffer issue sorted out before 0.6.0 release.

Regards,
Punky
