Latest working kernel version: unknown
Earliest failing kernel version: 2.6.25.4
Distribution: LFS 6.3
Hardware Environment: Acer Extensa 5220. Gr. card Intel 965GM X3100 Software Environment: intelfb compiled in kernel
Problem Description:

Steps to reproduce: boot with acceleration enabled.

I cannot get working text HW accel in intelfb framebuffer. Framebuffer without accel is working good.

I've got this is dmesg:
