The unichrome DRI driver is sending unaligned data which confuses the DRM
kernel module.

This is what the dri driver is flushing (via_ioctl.c:854):

0010:   430f0484  44390363  00000000  ffbf0505

dmesg shows this message:
[drm:via_verify_command_stream] *ERROR* Invalid / Unimplemented DMA HEADER
command. 0x430983f1

Tested on KM400 and CX700 mesa 6.5.1 and 6.5.2
