It seems as if the boot loader isn't initialising something properly.

If I boot rEFIt first, then the NetBSD Boot loader boots and runs A-OK.

If I power down and try booting the NetBSD boot loader first, then it
displays a whole bunch of address ranges in a "mem[]" array and hangs.
I can take a photo of this if anyone's interested.

However as of yet I've been unable to get the kernel to set the video
mode correctly.

Most interestingly if I do some playing at the boot prompt first such
that there is lots of white text in the small centre area, then try to
boot, the lines of green dots overwrite the top about 1/3 of the screen
leaving the lower portion of the white boot loader text still visible:
