To exclude as many components as possible, I tested this in single-user
mode (ie, init S) - as I mentioned in my original message.  Hence, X was
not running at all.  The only component of the DRI infrastructure that I
can't easily disable is AGP, as AGP support is compiled into current FC
kernels, instead of being modules.  (I can recompile the kernel without
AGP if you think it would be worthwhile to test that.)

For completeness sake, I did two more tests:

* Runlevel 3 *without* X: same behaviour as in single-user mode; ie, the
screen is blank, but I can issue shell commands and CTRL-ALT-Delete
works.  However, there is no beep when I press CTRL-G.

* Runlevel 3 with X started, but DRI disabled: The screen remains blank,
as before, but I don't seem to be able to issue shell commands and
CTRL-ALT-Backspace (to kill X) doesn't seem to work.
