Jaunty -RT testing

[Joseph Reagle]

As an aside, while I wasn't comfortable with with Jaunty RT oddness, I don't think NaturallySpeaking in a VirtualBox Machine requires RT, just low-latency. So I actually tried Intrepid again and built a kernel [1] with the following settings. I'm also using the new vbox 2.2b1 [2] -- with much improved USB performance -- and things seem quite good.

CONFIG_MCORE2=y
# CONFIG_NO_HZ is not set
CONFIG_HIGHMEM64G=y
CONFIG_HZ_1000=y
CONFIG_HZ=1000
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT_VOLUNTARY is not set
CONFIG_PREEMPT=y
# CONFIG_PREEMPT_RCU is not set
# CONFIG_PREEMPT_TRACER is not set
# CONFIG_DEBUG_KERNEL is not set
