kgzip uses 'gzip -9'.
However, this is all rather immaterial, as the 'asr' driver can be built
as a module. Put it on a floppy, stick it in, say 'load asr.ko' at the
loader prompt. No kernel rebuilding, compressing, or any of that crap.
Also relevant is that the 'asr' driver is *already* in GENERIC.
