I just have "fbdev" in the xorg.conf. Certainly not the best choice but it seems to be the most generic setup without having to tweak every combination of user-space release and kernel version and hardware variant.
Section "Monitor"
Identifier "lcd"
VendorName "BOE"
ModelName "W677L"
Option "Rotate" "right" # use TILER rotation
DisplaySize 111 62 # LCD size in millimeters
EndSection
Section "Device"
Identifier "display0"
Driver "fbdev"
Option "Monitor-DSI-1" "lcd"
Option "HWcursor" "False"
EndSection
Of course the kernel config uses DRM_OMAP:
