3.12-rc1 for N900 compiles and works (also display) here with binutils
2.23.2.

I think this is because the panel driver has changed, and the old one
was deleted. You need to change your kernel configuration with something
like below:

-CONFIG_PANEL_ACX565AKM=y
+CONFIG_DISPLAY_PANEL_SONY_ACX565AKM=y
