This code will be turned on with the TWO options
DEVFS and SLICE. (see LINT)
Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes.
/dev will be automatically mounted by init (thanks phk)
on bootup. See /sys/dev/slice/slice.4 for more info.
All code should act the same without these options enabled.

This code does not support the following:

Persistance. (My head is still hurting from the last time we discussed this)
ATAPI flopies are not handled by the SLICE code yet.
When this code is running, all major numbers are arbitrary and COULD
be dynamically assigned. (this is not done, for POLA only)
Minor numbers for disk slices ARE arbitray and dynamically assigned.
- Set the correct value scp->font_size in init_scp().
- Set scp->font_size to FONT_NONE for VGA_MODEX.
Interim fix for a font problem:
- A kludge to display the correct font on some video cards.
We should be able to load multiple fonts to the VGA plane #2 and switch
between fonts by setting the font select register in the VGA sequencer.
It appears that the current code isn't functioning as expected on
some VGA cards (I have reports on Millenium and Mach64 cards). This is
either a bug in syscons or a hardware compatibility problem ;-<
This kludge will always load only one font set at a time and always use
the font page #0 on the plane #2. It is an interim kludge until
we find the exact cause and solution.
Small adjustment for mouse cursor handling:
- Turn off the mouse cursor early when changing video modes.
Video mode switch fixes:
- Stop the screen saver when changing video modes.
- Enclose the critical section with a pair of spltty()/splx().
- A kludge to prevent scrn_update() from accessing video memory in less-
critical sections in video mode change; artificially turn on the
UNKNOWN_MODE flag.

"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.
Most uses of time.tv_sec now uses the new variable time_second instead.
gettime() changed to getmicrotime(0.
Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).
A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.
Add a new nfs_curusec() function.

- A kludge: initialize scp->xpixel and ypixel even in the text mode.
If the console enters the `unknown' graphics mode via the ioctl KDSETMODE

if you decide to use any codes outside the range of 0xc0-0xdf,
the mouse cursor may not look good, because of the way VGA displays
characters in 9-dot-wide character cells.
