关于framebuffer,T410s的配置

[zhangmms]

我参照网上uvesafb的设置，完成framebuffer的设置，但是uvesafb不能支持我的T410s的1440x900的分辨率。以下是我的系统信息：

zmm@Gentoo ~ $ dmesg | grep -i uvesafb
[ 0.000000] Command line: root=/dev/sda5 video=uvesafb:1280x800-24,mtrr:3,ywrap
[ 0.000000] Kernel command line: root=/dev/sda5 video=uvesafb:1280x800-24,mtrr:2,ywrap

zmm@Gentoo ~ $ dmesg | grep -i mtrr
[ 0.000000] Command line: root=/dev/sda5 video=uvesafb:1280x800-24,mtrr:3,ywrap
[ 0.000000] MTRR default type: uncachable
[ 0.000000] MTRR fixed ranges enabled:
[ 0.000000] MTRR variable ranges enabled:

[ 0.000000] Found optimal setting for mtrr clean up
[ 0.000000] New variable MTRRs
[ 0.000000] Kernel command line: root=/dev/sda5 video=uvesafb:1280x800-24,mtrr:3,ywrap
zmm@Gentoo ~ $

感觉好像是MTRR没有设置正确，请帮忙看一下。

补充以下
zmm@Gentoo ~ $ cat /proc/mtrr
reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back
reg01: base=0x080000000 ( 2048MB), size= 1024MB, count=1: write-back
reg02: base=0x100000000 ( 4096MB), size= 1024MB, count=1: write-back
reg03: base=0x138000000 ( 4992MB), size= 128MB, count=1: uncachable
reg04: base=0x0cf000000 ( 3312MB), size= 4MB, count=1: write-back

上面的1280x800是 能识别的最高分辨率，如果设置成1440x900就会变成640x400

补充一下，uvesafb把我的NVS3100M 认成MVS170M了，和这个有关么？
