I updated the git branch on my site --

 http://git.corpit.ru/?p=qemu.git;a=shortlog;h=refs/heads/mjt-dt-nographic

(two patches on the top).  This now includes the `make check' fix by
flipping the check (FW_CFG_NOGRAPHIC==1 vs ==0), more documentation
rewording (suggested by Peter) and Reviewed-by tags.

And yes, I dislike this mess too -- neither -nographic nor -display none
should be tied with guest serial port.  Better approach for the Ctrl+C
handling has been proposed by pbonzini. Better suggestions for FW_CFG_NOGRAPHIC
welcome.  Maybe something like -serial-console (linux has console=ttyS0,tty1)
which will be turned on by -nographic and which will be passed to firmware
as FW_CFG_NOGRAPHIC, and which can be used in -serial none case to check for
sanity.  But actually, -display none isn't that bad of a choice here (and
maybe we may also enforce non-none serial in case of -display none).

Thanks,
