You can probably use fs and gs because in the documentation for the
far pointer functions it says that fs and gs are used by the far
pointer and movedata routines (but don't assume that fs and gs wll
stay the same across function calls.  If you don't use these two
functions then you can _PROBABLY_ use fs and gs freely.
Input/verification would be appreciated here (I wondered this same
thing.
