Here's my output:

+% sudo ./drm-test 
Allocated 32MB with handle=0x00000000dc595000
Added 1024KB map for ring buffer with handle=0x00000000dc595000
ring=0x00000028300000, contents=0x000000003c66c369

I guess those are the expected results of the test given what we've seen previously...

I'm running on an Intel x58 board, i7 processor.  This is on the UP i386 -CURRENT kernel I built.
