Sorry, I had missed your report until now.
You have an Apple eMac G4 (1.25 GHz PowerMac6,4).
When you boot OpenBSD/macppc, your screen goes blank here,
root on wd0a (e4d1ce90095ba4d8.a) swap on wd0b dump on wd0b

My PowerBook G4 (1.5 GHz PowerBook5,4) works well,
root on wd0a (7f743336b2c4e92e.a) swap on wd0b dump on wd0b
radeondrm0: RV350
[drm] *ERROR* Unable to locate a BIOS ROM
radeondrm0: 1280x854, 32bpp
I suspect that your "1024x768, 16bpp" mode doesn't work with your
eMac's internal display. Your "16bpp" looks strange. Until now,
I believed that OpenBSD always defaulted to 32bpp.
I don't know if we are missing 16bpp support or have a problem
detecting modes (EDID), but the fix would require changes to the
kernel's radeondrm code. I don't know the fix.
Doing "disable radeondrm" in boot_config(8) might work around the
problem.

We skip this question on radeondrm, because it doesn't need the
xf86(4) driver. A macppc with ATI Rage 128 or Nvidia graphics would
need xf86(4).
