I have now tried that and I still get no compression on the drive.

The only thing my kernel reports when booting is
st: Version 20011003, bufsize 32768, wrt 30720, max init. bufs 4, s/g segs 16
and later on
st0: Block limits 1 - 16777215 bytes.
Could this be a problem with devfs? Maybe I should make a kernel without
devfs support and see how it goes.
