The IEEE math libraries try to open a resource called MathIEEE.resource.
If it exists when it opens and initializes it looks at various fields in
the resource structure. One of those fields contains a pointer to the
68881/68882 base io addresses if the resource is for a 68881/68882. The
vendor of the 68881/68882 should be providing the autoconfig software to
set this up as well as the code that saves and restores the 68881/68882
registers for task switching.
