The file "LAST_MINUTE" in my ISO of NetBSD 3.0 warns as follows:

My questions are twofold:

My i386 box has 4GB. So the above applies to me. Sounds like that means
I'll have to compile from source instead of just do the binary install.
Is that correct?

Or might I be best advised to patiently await some future version of
NetBSD 3.0.X wherein the above might be patched?
