neofb: 1024x480 (picturebook) support

hi,

here's a small patch for the neomagic framebuffer driver, to add support for the 1024x480 LCD found on early models of sony vaio picturebooks.

this is similar to the libretto 800x480 hack already included in the driver. below is for 2.5.66+, here's links to it, as well as a version for 2.4 which also backports the libretto support:

http://gerard.st/~jeff/neofb/neofb-picturebook-2.4.patch
http://gerard.st/~jeff/neofb/neofb-picturebook-2.5.patch

both patches create Documentation/fb/neofb.txt .

i calculated the numbers based on the X modeline. fbset says:

mode "1024x480-92"

    # D: 64.998 MHz, H: 48.362 kHz, V: 92.118 Hz
    geometry 1024 480 1024 2560 8
    timings 15385 168 8 32 11 144 2
    hsync high
    vsync high
    accel true
    rgba 8/0,8/0,8/0,0/0

endmode

Great thanks! I haven't had the time yet to back port the libretto support so I'm especially thankful for that! I hope James will forward the patch to the correct people for inclusion.

Best regards,
