Windows CE, seeing as it runs on ARM processors, might work. Win32 and WinNT won't run. WinPE won't run either.
Ubuntu might be a shot, but it doesn't make any sense to port Ubuntu specifically. One of the things Ubuntu does is good hardware detection, compared to some other distros. Given that we have a single hardware set with the F-200, there's no reason for a distro with good detection. Also, a custom GUI would be better than KDE.
I don't see how any version of the Mac OS would run on an ARM system.
