Has anyone jumped through the hoops to get DRI to work on NetBSD?

I'm suddenly enjoying doing some openGL programming, and would like to have 
faster than snail speeds.  :)

There seems to be no (working) kernel driver in xfree86 for NetBSD, mostly due 
to letting bits fall into disuse.  The major problem seems to be that 
vm_offset_t is defined as vaddr_t, which is an integer, while the DRM driver 
bits assume it is a pointer, and can be compared to NULL and used as a void 
pointer.

Thanks,
