Bug Description

"""
From: Stuart Langridge <email address hidden>

Can the iso itself detect when it's booted on an i386 system and say
"Hey, you've got the modern Ubuntu disc; what you needed was the
slightly older ("32-bit") disc, which you can get from www.ubuntu.com"
in some sort of nice way? Obviously it's irritating to have downloaded
(or got from someone) a whole disc that doesn't work, but making it
point you in the right direction to fix the problem would be nice.
"""

gfxboot-theme-ubuntu has the ability to detect 64-bitness, but this isn't wired up properly as yet.

I haven't looked at the gfxboot code, but if it's helpful, here's what the kernel uses for detecting LM:
