Not really.

The main problem is that for the most part it's a pile of crap that
nobody wants to look at, so drivers getting added there see basically
no real review.

I have no doubt that more of these will come. Chris Metcalf is currently
looking for a home for his tilera hypervisor drivers, and we have the
microsoft hyperv drivers in drivers/staging, so they will hopefully
move to a proper place later. We also have similar drivers in other
places, e.g. drivers/ps3/ps3-sys-manager.c, drivers/s390/char/vmcp.c
or parts of drivers/xen.
