(actually this 2.6.9 mistakenly had newer DVB drivers patched in.
 I have now tried again with 2.6.10 instead. Sadly, no change)

% egrep _HOTPLUG= /usr/src/linux/.config
CONFIG_HOTPLUG=y

	I was hoping that I could do something like:

% sudo modprobe sp887x debug_upload=1

and maybe see something that might help.
