After some trials and tribulations and help from Andrew Morton and Junio Hamano (thanks), I was able to successfully test this patch as sourced from v2.6.19-rc4-mm2. There is still the problem that the framebuffer console doesn't work, the display is blank until X comes up, but at least it doesn't crash.

I'm suspecting a configuration problem, my configuration file can be seen in my post from 10/14/2006 as seen here; http://marc.10east.com/?l=linux-fbdev-devel&m=116085527611531&w=2, if anyone has some suggestions I'll be glad to investigate further.

Regards,

Wink Saville
