On Tegra chips, nouveau seems to be used for rendering only.

Can you check whether u-boot is updating the simple-framebuffer device tree node? There should be a /proc/device-tree/chosen/framebuffer@<address> directory containing status, width, height, etc. That would help to isolate the problem to either u-boot or the kernel.
