If you are in DOS, maybe there are some BIOS Interrupts that could do that
in a transparent way. ACPI comes also to mind, but probably will work, if
ever, on only recent MBs.
Otherwise, in DOS, you may also write directly to the Super-I/O controller,
without the need for a driver. If however you want a solution that should
work with many Super-I/O chips, you have to get their datasheets and/or
programming manual and have to implement code that identies the chip and the
switching with the appropriate sequence of cookies. Tedious works...
I know of some work for the Linux kernel to identify the Super-IO chip.
I only teste the smcio code on one mainboard.
