m68k8k is the same as the other m68k ports. The win there should be
obvious :-)
I modified ld.so some time ago to allow mixing of 8k/4k binaries/libraries.
I HIGHLY recommend that you now install the latest hp300 binary snapshot
available at:
ftp://ftp.netbsd.org/pub/NetBSD/arch/hp300/snapshot/
...there are special instructions that you need to follow for updating
a 4k system to an 8k system.

Yes, the hp300 can use 8k file system blocks. The only problems exist
when you use a file system block size _smaller_ than the hardware page
size, which is 4k on the hp300.
