Here is the XFree86 point of view: If you want the result to be usable with XFree86, then just make sure that it will fit in with the AGP abstractions provided in XFree86's os-support layer. XFree86 drivers that need AGP GART functionality, like the i810 driver, use solely those interfaces. You can hide the OS-specific details in the Solaris part of the XFree86 os-support lyaer.
