I wrote too soon.  :-(

I finally re-started my daily updates, and built stable/7 at r203700.
At first, I had no trouble using the above options on stable/7 or
stable/8, but when I booted from the CURRENT slice, the laptop appeared
to lock up.  (And since I was on battery power, as this was during the
commute to work, I had an incentive to try to control the shutdown as
much as I could.)

Anyway, after booting single-user, disabling DRI in xorg.conf allowed
the use of X (built under stable/7) in head again.

But now it's looking as if enabling DRI on my laptop carries a
significant risk for an apparent lock-up regardless: as thing are now,
the keyboard and mouse appear to be unresponsive, I can't login via SSH,
I can't login via serial ... woops -- there it goes: I was able to login
from the serial port, and when I did that, xdm started up.

That's looking suspiciously like some sort of locking issue to me.

I'm about to start building firefox, but after that's done, I'd be happy
to get a bit of guidance on what to poke at or information to provide to
resolve this.

Thanks!
