Ok. A version of 'cvsps' which can correctly parse Larry's log format into patchsets is up on the website (www.cobite.com/cvsps). It's version 2.0b3.
Larry's timestamps actually made this hack really easy. All files committed with the exact time are recreated into a patchset. Here, for example is 'patchset 8156':
-------------------- PatchSet 8156 Date: 2003/03/05 03:11:19 Author: torvalds Branch: HEAD Tag: v2_5_64 Log: Linux 2.5.64
BKrev: 3e656ad75XghvjRCVNEGWy20cX0qwg
Members: ChangeSet:1.8156->1.8157 Makefile:1.340->1.341
(note, this is a pretty boring patchset, I just wanted to show it basically works).
The patchset id is in-sync with Larry's ChangeSet commits (but off by one from the beginning).
You can do: 'cvsps -s 8156 -g' to generate a diff of this entire patchset, and even get the correct results.

The checkin (Logical Tag x.yyy) log messages are currently not validated, and are discarded. Only the 'main' message with the BKrev: is associated with each patchset.

Seems to work.

Not necessary, each changeset is available via cvsps with 'cvsps -s <logical change number>' as well as searching by file, by date, by tag, by log message etc.

Uggh.
