I'm not sure of what you mean with "work in an X4.2" tree...

If you're wandering if the driver is binary compatible you must have in 
mind that a DRI driver is in fact 3 different components: a kernel driver 
(DRM), a 2D DRI aware driver (DDX) and the GL driver. The DRM is tied to 
your kernel version. Since the DDX driver is based on the XAA 
archictecture it should work with future version of XFree86 (in 
principle). The GL driver is entirelly a DRI business which I don't think 
it changed its API with the new release.

If you mean the code itself, you must know that the X4.2 tree wasn't yet 
merged in the DRI trunk.

Also have in mind that the actual mach64 branch is a partial X tree that 
is installed under /usr/X11R6-DRI/ with symbolic links to your previous 
/usr/X11R6 - which can have any 4.x version AFAIK.

I hope I haven't missed your question! If you have any question regarding 
the meaning of any of the terms here please check the DRI-Devel-FAQ at
