Well, it's a diskless machine booting via tftp. But it doesn't like a
tftpimage (probably not enough memory), and for one reason or another the
downloading of the kernel is painfully slow (takes a few minutes
to download the current 1.5 Mb standard kernel).

About just gzipping: from what I gather from Makefiles of other platforms,
you need to prepend some unzip-code to the kernel (piggyback). I can't
find this one in the kernel tree either. Or does a gzip self-extracting
archive suffice on the sparc platform (if such a thing even exists for

Do they crash or just take long to uncompress? Mine would be in the
mentioned category, being a Sparc IPC with 12 Mb ram.
