I'd recommend leaving CFLAGS and COPTFLAGS alone (I've only managed to 
make problems when I set these), but I would change CPUTYPE to your CPU 
Type, options are:

AMD CPU:   athlon-mp, athlon-xp, athlon-4, athlon-tbird, athlon, k6-3, 
k6-2, k6, k5
Intel CPU:    p4, p3, p2, i686, i586/mmx, i586, i486, i386

If you want to rebuild a custom kernel add this:
KERNCONF=FOOBAR

--------------------------------------------------------------
For your kernel config file comment out everything you don't need (make 
sure you have a "working" kernel b4 you buildworld), i.g:

cpu             I486_CPU
cpu             I586_CPU
device          eisa
device          atapifd         # ATAPI floppy drives
device          atapist         # ATAPI tape drives
all the SCSI Controllers
etc.
Don't forget to add in sound support etc. etc.

---------------------------------------------------------------
then buildworld:
# cvsup -g -L 2 foobar-supfile (set the cvs release tag to RELENG_5_3)
# cd /usr/src
# make -j2 buildworld && make -j2 buildkernel && make -j2 Installkernel 
&& reboot
test your new kernel, if it works drop down to single user mode
# shutdown now
# cd /usr/src
# make installworld
# reboot
If system is still working then mergemaster
# mergemaster
# reboot
Done.

rm -r /usr/obj/*
