Converting physical into virtual address

I'd like to develop a kernel module for FreeBSD, able to read & write directly to VGA text-mode screen buffer. I know that this buffer is located at 0xB8000 in physical address space. But in kernel I must address it using kernel virtual address space. Thus, the question is: how can I _correctly_
