Don't use intelfb, just use the standard uvesafb.

Here's my menu.lst part:
title=Gentoo Linux
    root (hd0,1)
    kernel (hd0,1)/gentoo/kernel dolvm crypt_root=/dev/sda4 lvm2root=/dev/mapper/root real_root=/dev/system/gentoo-root video=uvesafb:ywrap,mtrr:3,scroll:ywrap,1024x768-32 splash=silent,theme:KillBillTux-Grey fbcon=scrollback:128k console=tty1 resume=swap:/dev/system/suspend-swap quiet
    initrd (hd0,1)/gentoo/initramfs

I have the same card and it works perfectly this way

Good Luck!
