Description of problem:
After upgrading kernel to kernel-2.6.16-1.2069_FC4, bootup fails at point when
it would normally switch over to graphical boot. This problem does not occur
when booting with kernel-2.6.15-1.1833_FC4 or earlier.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Select kernel-2.6.16-1.2069_FC4 at startup.
2. Screen goes blank and video feed is lost.
Bootup to graphical login screen.
The machine is accessible via ssh even when screen is blank. Also, if booting
in text mode (initdefault=3), the boot process will proceed to a working VT
login prompt. When logged in, startx will start the KDE environment normally.
Apparently different from bug #169637 in that workarounds listed there do not
work here (e.g. commenting out load "dri").
Differs also from bug #187627 in that the kernel appears to have booted
successfully (ssh working, etc).
