I'm re-building with HRT on now, but I just noticed another side effect of
2.6.18. I have an led sniffer plugged into the pl2302 usb<->serial
adaptor laying where I can see it, and all leds are red, as if the
interface has not been inited properly. And I don't see it being
initialized in the dmesg. I thought the default was to build it. Yup,
pl2303.ko is present in the /lib/modules trees all across the board.

Any ideas on this one folks?
