I use

makeoptions     COPTS="-O3 -mcpu=21164a -Wa,-m21164a -mmemory-latency=main \
		-fsched-interblock -fsched-spec -fsched-spec-load \

in my kernel config file (I added the continuation lines myself - are
they valid in a config file?).  I got that rather heroic set of options
from the port-alpha list in the past, but the -Wa,-m21164a should be
redundant on -current compilers.  I don't know if those would produce
something that would run better on a 21264 though...
