Just add it to the list of boot options that you can specify after the kernel name, like the x refresh rate etc.
Yes, we know that. We are talking about the default behaviour, that is, what happens when you don't type something. I'll say it again:
"It should be enhanced" or "It should not be enhanced" by default
is an irrelevent arguement.
For users with old hardware, they do not have a choice. They MUST use it as non-enhanced, which is why the default behavior should be non-enhanced to prevent needless crashes and complaints from new users.
Personally, I like using the enhanced behavior on my Pentium-3 system. However, I do not consider it to be a big deal to type "enhance" at the end of my boot prompt.
If you really care that much, maybe you should edit the boot floppy config file or remaster the cd so that it will load up in enhance by default.
