with the point that most users of __ISAPNP__ will have to be fixed)
re-enabling the required EXPORT_SYMBOL's won't be hard for him.

- else if dimensions of the display are known, use that to estimate xres and
- else if modelist has detailed timings, use the first detailed timing
- else, use the very first entry from the modelist

and less preferred timings are entered last. (Detailed, VESA,
established/standard).

vesafb occassionally gets the size wrong when setting the mtrr. When X or DRI

arbitrary refresh rate (eg. in the following sequence of refresh rates: 70 60
53 85 75, 53 is selected).
This patch fixes the function so that it looks for the closest mode as far as
both resolution and refresh rate are concerned. The function's first argument
is changed to fb_videomode so that the refresh rate can be specified by the
caller, as fb_var_screeninfo doesn't have any fields that could directly hold
this data.

"I've tried with video=atyfb:debug and video=atyfb:debug,mode:1280x600, \
nomtrr.
In both case, the screen stays black, but seems divided into 4 vertical bands.
Some white lines pop up randomly on each vertical band."
The problem is a combination of an incorrect xclk plus lack of timing
information. The adapter is attached to an LCD device that can do 1280x600
(which is not a standard resolution). The global mode database does not have
an entry for it. Fortunately, the Video BIOS contains the complete timing
info for this display, however, atyfb is not making use of it.
Add support to get the timing information from the BIOS, if available.
[PATCH] fbdev: Remove software clipping from drawing functions
Remove software clipping from imageblit, fillrect and copyarea. Clipping is
not needed because the console layer assures that reads/writes doest not

hide bugs, if they do exist.
[PATCH] fbcon: Initialize new driver when old driver is released
If machine has more than 1 driver installed, and they all drive the same
hardware, it's possible that the driver's fb_release() method will attempt to
restore the hardware state to the initial state. This will leave the new
driver in an undefined state. To prevent this problem, initialize the new
driver by calling fb_set_par() when the old driver is released by fbcon.
[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant. The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.
Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank. For drivers that do, they can fill up this field with their own
version.
The end result is a smaller code size. And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.
nvidiafb didn't fully hook-up the code it borrowed from X for doing flat
panel dithering (this is useful for 6 bits panels). This adds a driver
option to force it, and by default "reads" the current value from the chip
to get the firmware setting. It significantly improves the quality of
images on the iMac G5 I have here (though the X driver doesn't yet "read"
the current value and defaults to 0, so you have to add Option "FBDither"
"true" to your X config file to get that, I'll try to fix X.org to "read"
the default unless specified asap).
