Ok, now that is odd.  I assume when the installer is being run, it says
Name: Xpmac when doing the inital X setup?  The code that's failing would
seem to be:
+#ifdef __powerpc__
+    int i, fh, rc = 0;
+    const char * name = "/dev/fb0";
+    char *server_name = "XF68_FBDev";
+    if (!(fh = open(name, O_RDONLY)))
+       rc = 2; /* Failure */
+    if (!rc && ioctl(fh, FBIOGET_FSCREENINFO, &fix))
+       rc = 2; /* Failure */

Which means no frame buffer, and most likely MkL.  We should begin working
on the installer changes to support APUS in a day or two.  Mind sending me
privatly the emails of a few people that would wish to test things out?
(or would the linux-apus list be interested?  I could subscribe for a
little while.. :))
