I have been running a 750 MHz Duron for several months now on 4.2, 4.3
and -current with no problems (except sometimes recently on -current,
but that is not the hardware's fault.)
The first part of my dmesg is

I have built and run with GENERIC kernels as well as specialized ones.
The top of my config file looks as follows:
-----------------------
machine i386
cpu I686_CPU
ident XXXXX
maxusers 32
options NO_F00F_HACK
options NO_MEMORY_HOLE
options CPU_WT_ALLOC
#
# BLKDEV_IOSIZE sets the default block size used in user block
# device I/O. Note that this value will be overriden by the label
# when specifying a block device from a label with a non-0
# partition blocksize. The default is PAGE_SIZE.
#
options BLKDEV_IOSIZE=8192
options PQ_CACHESIZE=512 # color for 512k/16k cache
...
--------------------------
I am not sure whether one should use the PQ_CACHESIZE or not and if this
is the "right" value, but it all works for me.
I set the following in my make.conf
CPUTYPE=k7
but this is almost certainly not necessary either.
If you are running with a GENERIC kernel, then the above should work. If
you can't get the GENERIC kernel to work, then I would wonder if there
are problems elsewhere, something not set properly on your motherboard
maybe? My (cheap) Transcend TS-AKT4 motherboard uses the VIA chip set. I
don't know what other chip sets might support the Duron. I am only
using PC100 memory. With my drives, I get a 1hr and 5 min make world so
I am not complaining too much.
I would be happy to send you my complete config file, if you think that
would help.
Good luck.
