We cannot assume that the BIOS will be correctly setting up the hardware, so
set some bits in various display registers to enable video output.  Allow an
advanced user to specify a frambuffer size, rather then probing the BIOS.  All
of these fixes were prompted by the OLPC effort.

ACPI drivers like ibm-acpi are moving to the backlight sysfs
infrastructure.  During ibm-acpi testing, I have noticed that
backlight_device_unregister() sets the display brightness and power to
zero.

This causes the display to be dimmed on ibm-acpi module removal.  It will
affect all other ACPI drivers that are being converted to use the backlight
class, as well.  It also affects a number of framebuffer devices that are
used on desktops and laptops which might also not want such behaviour.

Since working around this behaviour requires undesireable hacks, Richard
Purdie decided that we would be better off reverting the changes in the
sysfs class, and adding the code to dim and power off the backlight device
to the drivers that want it.  This patch is my attempt to do so.

Patch against latest linux-2.6.git.  Changes untested, as I lack the
required hardware.  Still, they are trivial enough that, apart from typos,
there is little chance of getting them wrong.

Fix some possible unaligned accesses when accessing fields of 'image'
pointer.  Indeed this pointer was obtained by allocating a block of memory
that embeds a temporary array plus an image structure.  The temporary
buffer was located at the start of the allocated block and depending on its
size, the image structure which comes right after can be unaligned.

For example when using mini fonts (4x6) (cursor's width is 4 and its height
is 6) the temporary buf size is 6 bytes.

Therefore this patch moves the image structure to the start of the block
and moves the temporary buffer right after.  It makes 'image' pointer
always aligned and since the tempo buf is a buffer of char, it's always
correctly aligned as well.

It also fixes the file header alignement.

The backlight layer should be independent from the framebuffer layer.  It
can use the services offered by the framebuffer, but its absence should not
prevent the backlight/lcd layer from functioning.

  - Added a write_reg(_dly) macro. This improves readability when
