Fix the so called "static bug" in polling mode. Some desktop cards
have bad grounding characteristics which allow small static discharges
(or sunspots, we're not 100% sure which) to reach the bridge chip.
This causes the bridge chip to wedge/reset itself. There's no known
cure short of rebooting.
The bug manifests itself by the STAT_CHG return 0xff when read. This
is impossible because the upper bits are reserved (and therefore
zero). In addition, some of the lower bits are one only for memory
cards, which OLDCARD doesn't support, so if they are set, something

General corrections and fixings of the hardware list:

For cases where a driver has no manpage (and hence no &man entity),

this was done by examining driver manpages.
2. A number of devices which are i386-only are now marked as such,

architecture-specific directories.
3. Added hardware supported by the vpo(4), wl(4), awi(4), and bktr(4)

Use a critical region to protect pushing of the parent's npx state to the

fninit. Mundane null pointer bugs were not possible, because we save to
an "arbitrary" process's pcb and not to the "right" place (npxproc).

fork() were not preserved in the child unless an accidental context
switch did the pushing. Updated the list of pcb contents which is

missing. Copying is correct for pcb_dr*, and pcb_ext is already
