These won't be a problem. Both Delphi and FPC (for non-i8086) will skip the
$F directive as it's not necessary on 32- or 64-bit systems.
The object file won't be a problem for FPC on i386-win32 because it will be
a COFF file which is the default.

Aside from asking the company for a 64-bit variant or reverse engineering
the object file, no. How large is that object file? Maybe it's only a
relatively simple interface to the driver...

Are you really sure there's a driver involved? When you install it is there
a driver binary for both 32- and 64-bit? Cause 64-bit Windows *can not*
load 32-bit drivers.
