I went to Ladakh in Aug/Sept, mainly for a medical expedition but fitted in a couple of peaks at the end. Did the normal route up the main face on Kang Yatse I (6400m), and there was no evidence of it having been climbed recently - no footprints, prayer flags etc. The IMF fee is a nightmare when looking at it from this country, but I sorted it out in Leh. The guy in the office who sorted out my permit had summitted K2! The permit would have cost 2000Rs, but as a student got it for 1000Rs (£14). This was not a trekking peak, so should have cost 500 US Dollars! Got a faxed offical document from the IMF officer in Leh, so all was good! If you sort it out there, liaison officers are not needed for peaks below 7000m. I would add that there are reasonably good maps for Ladakh available from Editions Olizanes, Padum was on the map, so I suspect that the peak that the team attempted is on it.
