silo is able to handle compressed kernel like this. No need for builtin
gunzip in the kernel itself like for i386.

don't know mknbi-linux. Is it for netbios or alike ?
On sparc, you need to convert it into a.out format. Use elftoaout from the
sparc-utils package.
You can get the standalone kernel from the sparc bootdisks (named
"linux-a.out") for a net bootable kernel and tftpboot.img to get a kernel +
ramdisk image. The latter one is created using the piggyback command.
Take also a look at tilo (still available in sparc-utils) to build a TFTP
bootable image with ramdisk for sparc and ultrasparc at the same time (as for
tftpboot-2.2.1.img).
Hope this helps you.
