Well, that's not true. In fact I do have virtual consoles. On the Mac I need
to press ctrl+alt+fn+Fi, where i=1, 2, 3... 6 to get to one of the six
vconsoles I have. fn is the key that makes the top row keys act as function
keys:

As for Joel's question, trying to switch between virtual consoles several
times doesn't result in anything--the screen keeps staying black. And it's not
the system that *thinks* the screen is off. It is indeed off, as the following
command from an ssh session shows:
$ cat /sys/class/backlight/intel_backlight/bl_power
4
bl_power = 4 means the screen is off.
I sent a bug report on this issue some weeks ago, but it's not been considered
till now, so I wonder whether I sent it to the right place and whether it will
ever be considered:
