IMHO the GGI drivers specification must provide some kind of hook to 
call these OS dependent stuff. VBE/AF 2.0 have hooks to do some OS 
specific stuff, lamentably the hooks are the wrong functions, for 
example: No hook for PCI stuff. So I do it "by hand" in my FreeBE/AF 
driver (it means I have code for the PCI detection inside the 
driver). The next generation of VBE/AF drivers will fix it or at 
least I heard it.

What's a hook? just a function pointer in the main structure of the 
driver. The OS fills it with a wrapper for the OS dependent routine 
so the driver makes a call to it through the pointer. In this way the 
driver uses a defined interface (OS independent).
