Yes, I see this:
r300: DRM version: 2.8.0, Name: ATI RV530, ID: 0x71c5, GB: 1, Z: 2
r300: GART size: 509 MB, VRAM size: 256 MB
r300: AA compression RAM: YES, Z compression RAM: YES, HiZ RAM: YES

I didn't noticed the
radeon: Acquired Hyper-Z.
radeon: Released Hyper-Z.
that indeed get printed when RADEON_HYPERZ=1 is set, however I also noticed
that with openarena I get the same FPS with or without it.
