mmap() doesn't work for /dev/fb# ?

Hi,

I wonder if anybody know the mmap() works for the frame buffer devices in
general?  I have tried to do mmap() on the virtual frame buffer deivce
(drivers/video/vfb.c driver) and it doesn't seem to map out the correct
address to the memory allocated in the device driver.  Any clue will be
greatly appreciated.

Thanks.
