Heh, DOH!!  I did mean Gigs, not Megs.

We'll see on that, as I first tried out 64bit but didn't really notice a
huge difference compared to running 32bit, least on my system.  And
since I use flash and couple others (I think), I have to mix and match
some i386 packages as well.

Who knows, maybe I'll try 64 again with F10 and see what happens.
