Because qemuppc has no graphic emulation, remove console=tty0
and make it run into 3 run level. This can reduce boot time
for qemuppc booting.

Can we not fix the X scripts so that if an fbdev X server is in use and
the framebuffer device node does not exist, it just exits cleanly with a
suitable message and doesn't timeout on boot?
Cheers,
Richard

X scripts serve for all the boards. And we also can't assume all the
boards use the same
framebuffer device. So how to detect whether the framebuffer device
exists is board dependent.
Maybe we can see whether the device /dev/fb0 exists(it could be created
manually, so we should try to open it to verify)
or the file /proc/fb exists to confirm the framebuffer device. Anyway,
any modification should be
tested on all boards to see whether it works. I prefer to mark it as
todo task in 1.1

I know I'm ok with this strategy, since time is short in the
1.1 cycle. We can always open a bugzilla item to track this,
just to be sure it isn't forgotten. Preferably we'll get a
qemuppc with a framebuffer in 1.x timeframe and we won't need
this at all. Coming up with something generic and the amount
of testing required doesn't fit the timeframe that we currently
have for 1.1.
But in the end, this is up to Richard, this is just my 2 cents
worth.
