I've seen that too in the past, but I may have found a way that works.

A couple of weeks ago Slackware and Debian seemed to work for me. (qemu
0.13.0p1 on 4.9 amd64) If I'm not mistaken they both have a non-graphical
installer.
I removed the Slackware image but I remember it working fairly smooth from
the command line. (I didn't install a graphical environment on either)
Though I haven't really used it, I still have a Debian image around that
seems to boot up fine without the black/blank screen. (If I remember
correctly the black screen was there for, maybe, up to a couple of minutes,
during the initial install)
I used the following CD image:
$ ls Debian/*.iso
Debian/debian-6.0.2.1-amd64-netinst.iso
and the script I use is:
$ cat debian.sh
#!/bin/sh
qemu-system-x86_64 -no-acpi -soundhw ac97 \
-hda ~/thuis.lan/virtual/Debian/hd.img \
-net nic,vlan=0,model=e1000,macaddr=52:54:00:12:34:58 \
-net user,vlan=0
Perhaps the -no-acpi parameter does the magic.

see ksh(1) -> use ulimit to increase the size of the data area, e.g.:
ulimit -Sd 1048576
I hope some of this is useful.
