Ah yes, this is very nice, thanks.  The graphical console was also
*extremely* slow on VMware guests.  It could take 15 minutes to reach
the login prompt!

That said, it would be still be interesting to see if it is possible to
speed up the graphical console somehow.  The Linux kernel can also use
a graphical console, but it isn't nearly as slow as that of FreeBSD...
