only half of screen is visable during boot

[Jason Dravet]

I opened https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170450 a week 
and half ago and I have not received any response so I thought I would send 
an email here.  I have been using the rawhide kernel since 
(2.6.13-1.1600_FC5 and I am running 1615 now.  During the boot, only part of 
the screen is visable.  For example the monitor the is the lines and I can 
only see text in the asterik area.  The bottom of the area I can see is only 
the top half of the line.  It is like someone cut off the bottom of my 
monitor.

I have a Number Nine revolution 4 video card and a SGI 1600sw lcd panel.
