OK, it sounds that I should be able to easily enough build a kernel with
that off. However, I noticed no weird messages on my console, and
everything *except* the bootup from the newly-installed system appeared
to be fine.

I run a number of Debian systems here, and it is my general policy to
disable both APIC and ACPI on any uniprocessor system. Both seem to
have fits on certain hardware, even very common pieces of it.

I'll certainly do that, but my initial problem is a little different.
It's not even getting far enough to load *any* kernel. It seems as if
something is screwy with my bootblocks.
That's why I mentioned I could boot from my install CD and point its
root to /dev/wd0a -- but I cannot actually boot from the hard drive.
I am using GRUB to boot -- but not its NetBSD kernel feature which a) is
pretty lame on i386, and b) claims the amd64 kernel is in an
"unsupported executable format". I am doing it the same way as I do on
my i386 platform machines: a chainloader, which basically does exactly
what NetBSD's bootselect does -- read the code from the NetBSD partition
and run it. Works great on i386 (I get the standard netbsd boot prompt
after selecting NetBSD from my GRUB menu).
