Disabling the psplash screen, I see this error:
   Running postinst /etc/rpm-postinsts/gthumb.sh
   Failed to load file "/etc/gconf/gconf.xml.defaults/%gconf-tree-pl.xml": Error on line 363 char 9: Element 'dir' was closed, no element is currently open
I think this was a result of an incomplete [previous] startup, so I
tried with a fresh image.  This time, it made it all the way to X,
so I guess I was just too impatient (of course, it took almost 8 minutes
to get to X on a 2.4GHz Core-2 Duo!)

I'll continue with my experiment to see how this runs on qemux86

Sorry for the noise.  I do think a slight improvement in the runqemu
script can help with situations like this.  I had to edit the scripts
to add the 'psplash=false' kernel option.  With the attached patch,
you can do it directly:
   % SCRIPT_KERNEL_OPT='psplash=false ' runqemu qemuarm
