and can't get working intelfb module on it. Kernel config:

# cat /usr/src/linux/.config | grep FB | grep -v '#'
CONFIG_FB=y
CONFIG_FB_DDC=y
CONFIG_FB_CFB_FILLRECT=y
CONFIG_FB_CFB_COPYAREA=y
CONFIG_FB_CFB_IMAGEBLIT=y
CONFIG_FB_DEFERRED_IO=y
CONFIG_FB_MODE_HELPERS=y
CONFIG_FB_INTEL=y
CONFIG_FB_INTEL_I2C=y

# dmesg | grep intel
intelfb: Framebuffer driver for Intel(R) 830M/845G/852GM/855GM/865G/915G/915GM/945G/945GM chipsets
intelfb: Version 0.9.4
intelfb: 00:02.0: Intel(R) 945GM, aperture size 256MB, stolen memory 7932kB
intelfb: Non-CRT device is enabled ( LVDS port ).  Disabling mode switching.
intelfb: Video mode must be programmed at boot time.


I tried these kernel kernel options:
kernel /boot/kernel-2.6.24-gentoo-r3-b2 root=/dev/sda5 video=intelfb vga=0x318
kernel /boot/kernel-2.6.24-gentoo-r3-b2 root=/dev/sda5 video=intelfb:mode=1024x768-32@60
kernel /boot/kernel-2.6.24-gentoo-r3-b2 root=/dev/sda5 vga=792

and in all cases I see blank screen or screen with many scrolling
white lines.


Any chance to get framebuffer working on my laptop?
