About the brightness, from kernel 2.6.38 you can add to grub the following option:
video.use_bios_initial_backlight=0
And remove echo 10 from rc.

If you have time, could you please load the module btusb and check if you observe this intermittent high pitch noise?
modprobe -a btusb
If it's enabled by default (check lsmod) try to disable the module (modprobe -r btusb) and check if the machine sounds different :-)
