Hi,

I think I've gotten 68LC040 macs to work well with 1.6.  Basically
go to http://edoneel.chaosnet.org/Downloads.html and pick
up the lc040-softfloat-20030106.tgz file, explode it overtop 
of usr/src, set MKSOFTFLOAT to "yes" and build away.  After
a while you have sets for the LC040 which seem to work
without glitches.  The setting of MKSOFTFLOAT is key here.  Set
to "yes" you get a software floating point build, unset or set
to "no" and you should get the same build as you would
get without the patch.

I've not heavily tested it yet so this is very much a use at
your own risk package still.

cheers
