Well I decided to simply enable #define DEBUG in the stram.c. Below
you'll see the result for video=atafb:vga16:

atari_stram_alloc: rounded size = 0004c000
atari_stram_alloc: after mem_init, swapping off, get_pages=00f80000

and then in atafb:

atafb_init: screen_base allocated at 00f80000, size=0004c000
set_screen_base(virt=00f80000, phys=01b80000)

and that's it. So atafb is perfectly OK, it just believes the
stram_alloc routine to return valid RAM.
