I think this is your problem.  Does SDL work when not using OpenGL
(I haven't tried the SDK myself yet)?

If yes, you could file a bug about enabling OpenGL for SDL for
Fremantle.

AFAIK kdrive is a (minimal) X configuration (and Xephyr is an X server
that works on top of X display instead of a real HW).

Extended input is related to XInput extension[1], maybe it needs to
be enabled in Xephyr or disabled in SDL?

AFAIK x86 SDK uses Mesa to do OpenGL in software (I think this is full
GL, not the EGL spec subset like on the target).
