    Hi all,

      I wanted to use VGA16 framebuffer on 2.3.x but couldn't. I've read
      some codes, and found the reason in arch/i386/kernel/setup.c:

      static struct resource vram_resource =
            { "Video RAM area", 0xa0000, 0xbffff, IORESOURCE_BUSY };
                                                  ~~~~~~~~~~~~~~~
      (This protects any other requests, even in drivers/video/vfa16fb.c.)

      Then, I changed it as:

      static struct resource vram_resource =
            { "Video RAM area", 0xa0000, 0xbffff, IORESOURCE_MEM | IORESOURCE_AUTO };

      and I met Tux penguin again. But, my box did hang up when loading
      pcmcia modules. Perhaps, my change might occur this problem. So,
      tell me more smart fix.

      Thanks,

            A.Yoshiyama <yosshy@debian.or.jp>
