OK, some questions to test for differences:
Have you installed LFS on the same computer with the same hardware connected?
Have you used the same version of LFS for both installations?
Have you got a possibility to look at the configuration files of the previous installation and compare them against the current installation?

This is the first time installing LFS on this system, the other system that I previously had LFS installed on is a 32-bit system. This new installation is 64-bit.

6.3 x86 version for the older system. 6.3 x86_64 (lfs-LiveCD with experimental x86_64 manual) for this new system.

The old system only has Gentoo on it now (aside from Windows), so no.

:\

...there was a question mark at the end - intentionally not wanting it to sound like an assumtion...

anyway

After your experience with LFS and Gentoo and probably more I think you can discern messages from/during init from those during the time the kernel boots up.
The latter you see with "dmesg" - the former appear in the syslog if so configured.

They should of course not be mixed - but it is rather impossible that init could have started (emitting messages) while the kernel is not yet finished booting.

The messages you have shown tell us that they are perfectly normal - from the kernel booting stage.
If you think something is not right then maybe you can describe it in a different way so we will see what you mean?

[edit] ...but I'll stay out of this now - only watching

so, besides the messages, what isn't working?
does the system fail to boot?

It does not fail to boot. The kernel boot messages are just mixing with init messages (or init starts before the kernel finishes booting).

IT seems to work fine ATM, I just wish I knew why the messages were mixing together.
