Yes, I see almost exactly the same thing (except that I haven't
noticed any processes which stay running during the freeze -- things
like keyboard and mouse activity in X or the console always freeze).
Mine could well be swap related too, though I have 128MB of memory.

I really think developers should be made to run -current on an old,
slow, crippled machines so they notice this kind of thing which would
be lost in the noise on their fast machines :-)
