Subject: vfb module

Hi,
I changed a little bit the vfb module to be used as a frame buffer in 
memory. I would like to use the mmap over the virtual framebuffer. I 
added a few line:
I allocated the buffer using
videomemory=(void *)__get_free_pages(GFP_KERNEL, 
get_order(PAGE_ALIGN(videomemorysize)));

and fixed the framebuffer info structure:

vfb_fix.smem_start = virt_to_phys(videomemory);
vfb_fix.smem_len = videomemorysize;

What is the virtual frame buffer meant for?

Regards Michael
