I applied the patch and tried booting. That failed (as expected) with a "bad pte" panic:

...
Trying to mount root from ufs:/dev/ada0s1a []...
start_init: trying /sbin/init
dumpon: /dev/da1s1a: No such file or directory
pid 40 (sh), uid 0: exited on signal 11
TPTE at 0xbf840258  IS ZERO @ VA 0804b000
panic: bad pte
cpuid = 0
KDB: enter: panic
[ thread pid 40 tid 100032 ]
Stopped at      kdb_enter+0x3d: movl    $0,kdb_why

I then reverted r244237. The domU now boots a bit further, but there still seem to be significant issues. Below is the complete log.
