Continuation of the benches.

nlap is the IBM thinkpad laptop with P3cpu and 256MB RAM
running on battery (550MHz instead of 700).

gnu_1 is the first configuration of gnu as an amd64:

	Athlon64 3700+ 2.2GHz 1024KB L2cache
	1024MB dual-channel DDR400
	ASUS K8T890-based mboard
	64-bit matlab 7.1 (v7sp3)
gnu was tested again after the memory was changed for a similar
specification (CL2.5,DDR400,2x512MB) that worked stably (the
original memory, of the gnu_1 test, was from a Dell computer
and didn't work stably -- perhaps it didn't report its details
properly):  the results were the same to 3 sig. fig.s

`one': is the P4 (32bit) for comparison, copied from the tests
of 2006-02-01:

        p4, HT, 3.0GHz, 512KB L2
        1G RAM
        linux-2.6.13 (gentoo system)

box_1 is copied from the earlier, 2006-02-01 test:

        amd64 3500+,  Venice core, 2.2GHz, 512KB L2
        1G RAM (dualch DDR400)
	ASUS VIA-K8T890-based mboard
        linux-2.6.15 (gentoo system)

box_2 is modified from box_1 only in having lost one stick of
RAM, thereby making it single channel mode (and assume we can 
neglect the difference in actual _size_ of memory..?)

box_3 is back to 1GB dual channel, and with the motherboard
changed for a nforce4-based Abit one with the same CPU and memory.


Results given are means of several (3-5) consecutive runs, and
are not given unless every test had the same time to within
about 2% between runs.
