I'm using a laptop (msi ms-1013 korean edition) with ati chipset and x200 onboard graphic card.
and installed gentoo 2007.0 x86_64

with this option
Code:
kernel /boot/kernel-2.6.20-gentoo-r8 root=/dev/hda3 vga=0x318


i can see a framebuffer console.
Code:
# dmesg|grep vesa
vesafb: framebuffer at 0xf0000000, mapped to 0xffffc20000080000, using 4608k, total 65536k
vesafb: mode is 1024x768x24, linelength=3072, pages=27
vesafb: scrolling: redraw
vesafb: Truecolor: size=0:8:8:8, shift=0:16:8:0


but with this option
Code:
video=vesafb:1024x768-24@60


followes are the result.
Code:
# dmesg|grep vesa
Command line: root=/dev/hda3 video=vesafb:1024x768-24@60
Kernel command line: root=/dev/hda3 video=vesafb:1024x768-24@60

# ls /dev/fb*
ls: cannot access /dev/fb*: No such file or directory

# fbset -i
open /dev/fb0: No such file or directory


and radeonfb does samely.

does anyone know why , and how to fix this?
