As another test you could "boot -a" the netbsd10 kernel and then point it to a netbsd-10 installed USB or PCMCIA drive as a root filesystem. While you probably already have everything after the boot pretty much covered, it's always nice to see it come up and run completely from a netbsd-10 filesystem :)
You should also be able to pick up a CF to laptop PATA adaptor, which would allow you to boot from a CF card. More usefully it should (*) allow you to boot NetBSD-10 on the system, install onto the CF card in the pcmcia slot, and then be able to move that to the IDE bay to boot, giving you a way to test a full NetBSD-10 install without overwriting the existing disk. *: "should" - potential hand waving and profanities regarding made up disk geometries and older BIOS behaviour.
