I'm missing some context here.

What per-device ioctls are being replaced?  Does this project remove
them or are they removed by another project?

Does this project also update the Xorg server to use the new ioctls or
is there a separate project that depends on these new ioctls?  If the
latter, then please specify.  If neither, then please explain.

What privileges are required to invoke the ioctls?

Do the I/O register interfaces duplicate what's available through the
pcitool (PSARC 2005/232) ioctl interfaces?  What's different about
these interfaces?

What do other platforms do?
