Safe mode does the same thing, but see below.

Unfortunately, that might not work. Windows will refuse to load xenpci.sys if 
testsigning isn't right, and because it integrates itself into the ata driver 
stack as an 'upper filter', when it fails windows might fail the whole stack, 
even in safe mode. I haven't experimented with driver load options that might 
still let the ata drivers work even if one of their filters is not loading...
