future.
Put fields in the class for the geom's methods and initialize the methods
of a new geom from these fields. This saves some code in all classes.
o Change the motion calculation to result in
a more reasonable speed of motion
This should fix the 'aiming' problems people have reported. It also
mitigates (but doesn't completely solve) the 'stalling' problems at
very low speeds.

o Handle the 'up/down' buttons some touchpads have as
a z-axis (scrollwheel) as recommended by the specs
o Report the buttons as button4 and button5 instead
of button2 and button4, button2 can be emulated by
pressing button1 and button3 simultaneously. This
allows one to use the two extra buttons for other
purposes if one so desires.

o Only use (and rely on) the extended capability
bits when we are told they actually exist
o Partly ignore the (possibly dated?) part of the
specification about the mode byte so that we
can support 'guest devices' too.

path. The basic problem is that we cannot set the single stepping flag
directly, because we don't leave the kernel via an interrupt return. So,
we need another way to set the single stepping flag.
The way we do this is by enabling the lower-privilege transfer trap, which
gets raised when we drop the privilege level. However, since we're still
running in kernel space (sec), we're not yet done. We clear the lower-
privilege transfer trap, enable the taken-branch trap and continue exiting
the kernel until we branch into user space.
Given the current code, there's a total of two traps this way before
we can raise SIGTRAP.
after a fork(2) in fork_trampoline(). By moving the epc_syscall_return
label immediately before the call to do_ast() in epc_syscall(), we not
only achieve that but also handle the detour through exception_return
when the frame corresponds to an asynchronous kernel entry. Hence, we
simplified fork_trampoline() as a side-effect.
related to breakpoints and single stepping into SIGTRAP so gdb(1) knows
why the remote target has stopped. In particular, gdb(1) needs to know
if the reason is something of its own doing.

fcntl() operations, including:

F_GETFD retrieve close-on-exec flag
F_SETFD set close-on-exec flag
F_GETFL retrieve file descriptor flags
For the remaining fcntl() operations, do acquire Giant, especially
where we call into fo_ioctl() as a result. We're not yet ready to
push Giant into fo_ioctl(). Once we do, this can all become quite a
bit prettier.

This takes time and time is already in short supply.

loading /boot/kernel's modules when a different kernel has no modules,
but you left your module_load="YES" in loader.conf...
