I did some more testing. I think the problem is that the
Mac OS NetBSD Installer can't access a disk beyond the
first gigabyte. For any filesystems (even ones < 1 GB,
created using Mkfs v1.47) that are entirely past the first
gigabyte, I get the following from the NetBSD Installer
Mini Shell:

  > mount /dev/sd1g /usr
  Error on SCSIRead(), # 5
  /usr : Invalid argument

Although I can create and mount with no errors filesystems
that span the first gigabyte, I'm guessing that the NetBSD
Installer would have an error the first time it tried to
access a block past the first gigabyte (though I haven't
tested that).

I didn't use sysinst. I formatted the disk with Apple HD
SC Setup 7.3.5 and partitioned it with pdisk (with my
NetBSD Root & Usr partition entirely within the first
gigabyte). Then I used Mkfs v1.47 to create my "NetBSD
Root & Usr", "NetBSD Swap" and other filesystems. After
installing the base system, I could boot into NetBSD
single user to complete the installation.

Thanks, I'll try the latest version.
