Wow! 1k is a pretty stout pullup. I'd experiment with 10k.

Last week I briefly fired up a board via Dragon JTAG that was built a
year ago but never run before. Everything went fine until I attempted to
debug. Board immediately took off running but I can't single step or
breakpoint. Didn't have time or need to pursue it then. Meanwhile a
JTAGICE-II was coming in the mail via Arrow's half price promotion.

Next time I attack that problem board I will have a Dragon, ICE Cube,
and the official JTAG-ICE mkII.
