OK, there look to have been some twa(4) driver changes since netbsd-5,
has the driver probed correctly on the working machine ?

The locking changes are only for a DRMKMS kernel, maybe look at whatever
is wrong with twa(4) first.

I would pull the RAID controller and check that X11 works with the
GENERIC kernel that you already have. You could try the DRMKMS kernel
at this point too.
