Unless you have a great reason to use the boot-small.fs, I suggest you use
the boot1.fs and boot2.fs floppies (I'm assuming i386 here).  It does not look
(at http://www.netbsd.org/Hardware/isa.html)   like the 3c905 isa is supported,
nor a 3c515 isa.  

As for ne2000, often each board comes with a dos utility that lets you set
the irq and i/o addresses.

ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-1.5/i386/INSTALL.html suggests:

Novell NE1000, or NE2000 Ethernet boards
          ne0  0x280     9
          ne1  0x300     10
     

Again, this is for i386, which is what I'm assuming you have.
