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.
