Just stuck them online.  Don't know what's going on with the big white block
in the X11 test... is gd writing to offscreen VRAM or something?

http://www.tbrowne.demon.co.uk/latencytest

These were taken with the standard Mandrake 8.1 kernel... 2.4.8... no
patches applied.  Parameters were as default for the run_xxx_test scripts,
but with 3 buffers.

Note that I had to modify the ALSA open code to get it working with the
Envy24... fails with a PCM write error #14 if try to use the device
"hw:0,0"... needed to change it to "plughw:0,0"... why?!?

Machine spec...

1.2GHz Celeron-II running at 1.5GHz
ASUS TUSL2-M motheboard (i815EPB)
512MB RAM
Seagate Barracuda IV (UDMA5)
Savage4 32MB AGP, XFree86 4.1.0

Results were pretty awful to say the least - Linux is doing too much read
ahead buffering, and too much write-latering...  If there's an LL+buffer
patch for 2.4.15 final, I'll give that a go...

- Tom.
