I applied both, but something is still amiss.  Just commenting out the 
two frees allowed the domain to start, but the kernel started printing 
messages about the page state of various processes being bad.

After applying your two most recent patches (reverting the commented-out 
free_pages first), the domain seems to boot, but then hangs at some 
point early.

Disabling vfb still works fine.
