Comment # 14 on bug 1135865 from Oliver Kurz

As discussed with sndirsch taking the bug to adjust the openQA tests.

The code change I did:

```
diff --git a/lib/bootloader_setup.pm b/lib/bootloader_setup.pm
index 8bec28900..6da0678d2 100644
--- a/lib/bootloader_setup.pm

         if (!is_jeos && !is_caasp && (check_var('ARCH', 'i586') ||
check_var('ARCH', 'x86_64'))) {
             push @params, "vga=791";
-            if (check_var("INSTALL_TO_OTHERS", 1) || !$args{pxe}) {
+            if (check_var('QEMUVGA', 'cirrus')) {
                 push @params, "video=1024x768-16";
             } else {
                 push @params, "xvideo=1024x768";
```

which I see as a cleaner way but might be disruptive. I will check how that
works out in different environments.
