Hello all,

I ran across a couple bugs in memdisk concerning hd images the other
day.  With the attached patch I've been able to successfully boot a
32MB gzipped hd image.  (I'll put the image up for a short while at
ftp://ftp.io.com/pub/usr/duanev/fdoshd.img.gz)

The pxelinux.cfg entry I'm using is:

    label fdos
        kernel memdisk
        append keeppxe initrd=fdoshd.img.gz

syslinux/memdisk is great, thanks Peter et. al.!

More needs to be done; the code has console I/O at the library level,
which isn't good.

This patch
- add a new pci_dev_info structure :
    It contains additional informations about the pci devices like
    the product/vendor name and the associated linux kernel module

- add a get_name_from_pci_ids() function in pci/scan.c
    This function reads a pci.ids file from the boot device.
    Then it assign for each pci device, its vendor/product name.
    You just have to put this file in the root directory of your
     isolinux/pxelinux (i.e the root directory of your tfptboot server
    if you are using pxelinux).

- add a get_module_name_from_pci_ids() function in pci/scan.c
    This function reads a modules.pcimap file from the boot device.
    Then it assign for each pci_device its linux kernel module.
    You just have to put this file in the root directory of your
     isolinux/pxelinux (i.e the root directory of your tfptboot server
    if you are using pxelinux).

- Add a call to get_name_from_pci_ids() into the pcitest COM32 module
- Add a call to get_module_name_from_pci_ids() into the pcitest COM32 module

- Fixing typedef struct { ... } s_pci...; by struct pci... {};
- Improving comments
- Fixing the memory allocation to prevent leaks

With this patch, pcitest.c32 act like lspci plus a bonus by displaying
the linux kernel module assiocated to each pci device.

A very simple module to reboot the machine.
