howdy, just updated my sources (via ctm, very simple!) to current, and am 
in the process of upgrading my kernel etc..  its been a while, so I made 
a bad mistake, I copied my new kernel over the old one (gah) but at least 
I had a very old one (year old) lying about that does work ok..

anyway, the new kernel panics and dies if I try to start an X session, 
or do any big compiles.  It goes like this..  anybody any ideas? 

panic: pmap_page_protect !PG_V

and a bit of a misnomer there too, because I get no crash dump.
