porting fb driver to 2, 6(fb_get_fix, fb_get_var)

Hi,
  I am trying to port one of our LCD display frame
buffer driver to 2.6 kernel.
  The old 2.4 kernel had these functions defined in
fb_ops
    fb_open:    
    fb_release:
    fb_get_fix: 
    fb_get_var:     
    fb_set_var: 
    fb_get_cmap:
    fb_set_cmap: 
    fb_ioctl:   

  But the latest 2.6 fb_ops has removed these and
there is entirely new set of functions. 
  I tried to go to list archives but I could not find
information. 
  What functions in 2.6 fb_ops should to used to
implement this old 2.4 set of functions?

Regards
Syed
