If your bootpd serves rp= entry correctly, there is no need to use
bootparams at all.  I'm using diskless MAXINE served by NetBSD/sun3 1.3
in next window.  /sbin/dmesg reports like;

 asc0 at asic0 offset 0x300000 priority 3: target 7
 xcfb0 at tc0 slot 2 offset 0x0 (1024x768x8) (console)
 Beginning old-style SCSI device autoconfiguration
 boot device: <unknown>
 nfs_boot: trying BOOTP/DHCP
 nfs_boot: my_addr=0xa3dda23d
 nfs_boot: my_mask=0xffffff00
