With this finding, in case of OMAP3 we have to use OMAPFB_WAITFORGO (breaking standard applications).

Applications using the standard fbdev API won't work with manual update
displays anyway. You need omapfb specific code to handle it so having
another small difference is not a big deal.

In DirectFB the that's trivial since there's already a simple omap
gfxdriver where you could override the default flip functionality with
WAITFORGO based stuff.

Or, as I said, you could add another standard ioctl and fix up userspace
to use it where appropriate and if the kernel driver supports it.

That sounds more appealing to me: there's no point in having
omap-specific interfaces if they can be standard.
