Thanks for the help (as always!), but you may be confusing two
different problems.  The X log is from my initial problem, where the
system comes up fine, but X won't start.  Sven showed me that I need to
enable KMS, and now X works fine.  The current problem is with the
console (which used to work fine!) - the screen goes (and stays) black,
shortly after the beginning of the boot process, although, as I've
explained, I can actually get a working system by waiting for the
completion of the boot and then blindly typing 'startx', which gets me
to a perfectly normal X session.

A good suggestion - thanks.
