port-macppc: what's at PA 0x04000000? (pearpc)

Trying to run NetBSD/macppc inside pearpc (v0.2pre from CVS), the
bootloader loads the kernel, says "start=800000", and then aborts:

	[IO/Generic] <Warning> no one is responsible for address 04000000 (write: 00000000 from 0097a59c)
	singlestep set from io.h:83, info:
	machine check exception and MSR[ME]=0.
	Abort (core dumped)

I wonder what's at (probably physical) address 0x4000000 of a PowerMac?
