The tftpboot image contains two kernels and a compress ramdisk.

The drivers and rescue disk are found in:
ftp://ftp.debian.org/debian/dists/slink/main/disks-sparc/current
The relevent files are:
drv1440-2.2.1.bin
resc1440-2.2.1.bin
drv1440-2.2.1-sun4u.bin
resc1440-2.2.1-sun4u.bin
(The sun4u versions are for Ultras.)
The tftpboot-2.2.1.image is made with "maketilo" from the tilo package.
It is made by converting the sparc and sparc64 kernels to a.out,
compressing them, appending them to the end of a small a.out program,
tilo, and setting some offset values in tilo.
A raw a.out kernel can also be used for tftp booting, as can an a.out
kernel with a ramdisk properly piggybacked onto the end.
