If you can find one my Oly C7070 will do 90% of what your asking for - speed will probably be the limiting factor but its not bad for a P&S but 7mp and includes RAW.
Just checked ebay and surprisingly there is one just listed - it says the memory is xD but it takes real CF as well. All my pics on WPF were taken with one and anything of mine from the last year on BF were digiscoped with it.
There is a buy it now option - I recommend you do - there were some comprehensive reviews on the net when it came out if you do a search.
