[945GM] Black screen shortly after startup

Kernel config (builtin)
With a recent kernel (from mainline git repo), my system boots fine, but
shortly into the boot process, the screen goes, and remains, black. This
occurs well out of the bootloader, but I'm not sure exactly where in the normal
linux startup it's happening.
There's apparently no GPU hang, since the boot apparently finishes normally,
and I can get a perfectly normal X session by blindly typing 'startx'.
My normal kernel config has AGP / DRM / Intel / Consoleframebuffer stuff (along
with just about everything else possible) built as modules. When I switched
that whole chain to builtin, the system comes up fine, without the black

Is this still seen on 3.2/3.4 era kernels ?
I don't remember whether the problem ever went away, but in any event, the original machine has been decommissioned, so I cannot answer the question; sorry.
Thanks I'll close the bug as obsolete as the driver has changed a lot since then
Hi, I know this bug was closed a while ago but I can confirm that it still exists on the 3.2 kernel (fresh debian7 install).
Please open a new bug for it
