No, they weren't. Just tried it now though. The kernel now prints
"Undefined instruction in kernel. Heavy man!" over and over again.

Yes, this one does. 16MB makes little difference though (except for the
obvious).

No, this is the NC. The A7000 reports 6 blocks.
 
The second of the two blocks is the wimpslot taken by the BtNetBSD
program.

Now, I don't want to wait for the desktop initialisation to complete, so I
was running fastboot from a desktop file. This makes a crucial difference
as the memory is in an entirely different state. If run from a desktop
file, only two blocks are shown. I guess one is system workspace and the
other is the wimpslot for BtNetBSD. After getting into the desktop and
running !BtNetBSD, 5 blocks are reported and what's more, IT BOOTS INTO
THE KERNEL! OK, it bombs out in the same way as on the A7000, but that
further than we've ever got before.

Running !BtNetBSD early on an A7000 doesn't work either. It reports only 2
blocks again. Different error though (Can't use array reference at line
2090)

Makes no difference. The parameters are in the FastBoot file.
