Created an attachment (id=57132) --> (https://bugzilla.kernel.org/attachment.cgi?id=57132) dmesg using Linus' HEAD of May 10th 2011
On a Toshiba laptop using an AMD Fusion GPU (SoC: E-240), I am unable to have screen turn on with KMS. It stays blank, even when starting the X server.
I tried with 2.6.38.5, Today's Linus tree, Yesterday's drm-2.6/drm-next, all to the same result.
Here is the lspci:
