Subject[PATCH] broken cfb* support in the 2.5.31-bk
Hi Linus, hello others,
please apply this.

line_length, type and visual moved from display struct to the fb_info's fix
structure during last fbdev updates. Unfortunately generic code was not updated
together, so now every fbdev driver is broken.

Thanks,
Petr Vandrovec
