With this setup, with and without patches, I can spawn two consoles
via:

/sbin/agetty /dev/hvc0 9600 vt100
/sbin/agetty /dev/hvc1 9600 vt100

(Strange thing is, the second one gives a 'password incorrect' error
on login attempts, while the first one logs in fine.  I do remember
testing multiple consoles just fine a year and a half back, so no idea
why this isn't behaving as expected -- but it mostly looks like a
userspace issue rather than kernel one.)

Right -- when I test this on the Fedora 11 VM I used back then, the
two consoles work just fine without these patches.  When I use
something newer (F14), I get the weird password rejection, with and
without your patches.

It's not a weird password rejection, it's probably not set as a secure
terminal :)

Try adding hvc1 to /etc/securetty on the guest.

Ah, of course :-)
