The dosbox IPKs in the pdaXrom feeds are not very usable actually. I would recommand to make a build of the current CVS configured with --disable-debug (I don't see what use it could have to play games) --disable-fpu / --disable-fpu-x86 may increase speed a lot (since ARM donsn't like floating point at all) and something like dynamic core (configure --help to find the exact flag) is totally useless on XScale CPU, so better disable it and make smaller and faster binaries (you can strip them as well). Then you shall run dosbox -startmapper to remap keys (they are quite messed up by default, no Fn working ... but you can easily rebind everything in the mapper with a nice dos-like GUI !) and it should run Frontier Elite okay.
