I was using this:

bin/qemu-system-x86_64 \
   -M pc_q35 -L q35-seabios/out \
   -usbdevice keyboard \
   -hdd ./Fedora-14-x86_64-netinst.iso

This patch does indeed fix the problem for me, thanks for sending it !
The only small observation I have is that you seem to name all three
UHCI devices "ich9-usb-uhci1". There's probably a better way than my
patch below (on top of the one you just sent), but here's the general
idea :)
