I've just submitted a version of libsdl1.2-1.2.15 to the fullscreen ticket. I don't know if this is usable on Fremantle, it builds in a CSSU-T Fremantle X86 scratchbox target. I won't post links here as it is not an "Extras" package as Chess, Marble etc depend on it.

EDIT: Won't build on Leste atm:
_XData32 redefined.
debian/compat needs to be 5+
dhinstall throws error about missing sdl-config-1*..that's already in the correct folder
More packaging errors.

Will rebase patches on current Debian version to pull in current packaging over the weekend hopefully.
