There is more than a warning message, as I already reported in this bug
(and sorry for not having also reported to #614169, doing now):

Anyway, now that vgabios/0.6c-3 was uploaded, including the QEMU patches
to vgabios (see #614200), after having manully added the symlink for
vgabios-stdvga.bin [1], the following works as expected as normal user:

  $ ln -s ../vgabios/vgabios.stdvga.bin /usr/share/qemu/vgabios-stdvga.bin
  $ qemu-system-x86_64 -enable-kvm  -rtc base=localtime -name XP-Pro-En \
     -m 512M -k en-us -soundhw ac97 -usb -usbdevice tablet -vga std \
     -vnc localhost:9,none -monitor stdio -runas luca \
     /home/luca/xp-pro-en_BioEdit.img

[1] I am wondering if QEMU should not directly look where the various
    vgabios files are instead of symlinking them...  Yeah, I know the
    filenames are different :-(

Two notes: first, `qemu -enable-kvm` is slower than `kvm` and, second, I
have not tested it for long uptimes yet, sorry, but still with Firefox +
Flash video on YouTube.

Thx, bye,
Gismo / Luca
