felix probably was thinking about userspace drivers ...
for kernel questions you could have posted your kernel .config...
but anyway, see here for what knobs to twist to get your kernel do
kernel mode setting:
all kernel-graphics support is consolidated into i915 module.
fbcon is used by i915 to display the console.
all other kernel framebuffer-drivers are not to be used together with
the i915 module.
the whitescreen you encounter is probably a bug.
to get further with debugging this:
try to restart with i915 and fbcon built into the kernel and modesetting
switched on (in your .config or via kernel commandline: i915.modeset=1 )
as well as the kernel commandline drm.debug=12 (probably needs some
debugging option for drm turned on in your .config )
then post your resulting dmesg here and/or on
dri-devel at lists.sourceforge.net (which is the list mentioned in the
kernel MAINTAINERS file for the drm drivers )
if it is very urgent for you, you could also proactivly check out if it
is a regression or never worked for you by checking the kernels back to
2.6.29 (introduction of kms) for that turning-white symptom you are
