Make more drivers use the "mode_option" parameter. This one is quite new
so drop the old "mode" parameter before someone starts using it seriously.

Don't treat valid modes returned by fb_find_mode() (best-fit modes, default
modes or the first valid mode) as errors.
Currently, when fb_find_mode() finds a valid mode belonging to one of the
above-mentioned classes, uvesafb will ignore it and will try to set a 640x480
video mode. The expected behaviour (introduced by this patch) would be to use
the valid mode returned by fb_find_mode() instead.

Some cleanups in uvesafb:
- The custom module_param() get/set functions don't need to be inlined
since it is referred to via a pointer in a struct.
- don't end a #define with a ';'
- remove one of the single quote marks in "''ypan'"

Mark uvesafb_init_mtrr() as __devinit since its caller is __devinit
and since it accesses __devinitdata.
WARNING: vmlinux.o(.text+0x4df80e): Section mismatch: reference to .init.data: (between 'uvesafb_init_mtrr' and 'uvesafb_show_vbe_ver')
Variable 'blank' cannot be __devinitdata since it is referenced in an
fb_ops method that could be called at any time.

uvesafb is an enhanced version of vesafb. It uses a userspace helper (v86d)
to execute calls to the x86 Video BIOS functions. The driver is not limited
to any specific arch and whether it works on a given arch or not depends on
that arch being supported by the userspace daemon. It has been tested on
x86_32 and x86_64.
A single BIOS call is represented by an instance of the uvesafb_ktask
structure. This structure contains a buffer, a completion struct and a
uvesafb_task substructure, containing the values of the x86 registers, a flags
field and a field indicating the length of the buffer. Whenever a BIOS call
is made in the driver, uvesafb_exec() builds a message using the uvesafb_task
substructure and the contents of the buffer. This message is then assigned a
random ack number and sent to the userspace daemon using the connector
interface.
The message's sequence number is used as an index for the uvfb_tasks array,
which provides a mapping from the messages coming from userspace to the
in-kernel uvesafb_ktask structs.
The userspace daemon performs the requested operation and sends a reply in the
form of a uvesafb_task struct and, optionally, a buffer. The seq and ack
numbers in the reply should be exactly the same as those in the request.
Each message from userspace is processed by uvesafb_cn_callback() and after
passing a few sanity checks leads to the completion of a BIOS call request.
