I've had similar problems lately, using a CVS snapshot from
2005.10.02.  I wiped my hard drive and reinstalled everything, saving
everything important from my homedir first, especially ~/News.  After
doing so, none of my gmane groups were showing new messages as unread,
though I could still browse them.

Adding (nntp-marks-is-evil t) to the options for gnus-select-method
seems to make things work.  I had tried moving my ~/News/marks folder
somewhere else, but this caused Gnus to throw the following error when
starting up.
