I did as you said, and the same error:

I think Im going to reinstall Fedora Core and then try.

No need to reinstall, that is most likely not going to change anything.

I think your kernel config doesn't include the module that is missing (sata_sil).

You have two options:

either

a) When you do "make xconfig" you can select the needed modules yourself.

or

b) Copy one of the pre-made config files from the config directory - this is the option I would suggest and will describe below.

Assuming option b) from above and that you have the kernel-source package installed here are the steps to use:

1) cd /usr/src/linux-2.4
Change to the source directory

2) make mrproper
Clean out old junk

3) cp configs/kernel-2.4.22-i686.config ./.config
Copy the config file that matches your system best. You are not describing your system so I don't know which one you should choose, but they should be fairly self-explanatory

4) make oldconfig
Check the .config file

5) make dep clean bzImage modules
Build the dependencies, the kernel and the modules

6) su -
Become root

7) cd /usr/src/linux-2.4
Change to the source dir

8) make modules_install
Install the modules

9) cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.22-1.2135.nptlcustom
Copy the kernel to the boot directory

10) cp System.map /boot/System.map-2.4.22-1.2135.nptlcustom
Copy the symbols file to the boot dir

11) mkinitrd /boot/initrd-2.4.22-1.2135.nptlcustom.img 2.4.22-1.2135.nptlcustom
(one line) create the boot image

12) vi /boot/grub/grub.conf
Edit the grub config file, you will need to add a new entry by copying the 4 lines that make up an entry and edit them, so if you e.g have

title Fedora Core (2.4.22-1.2135.nptl)
        root (hd0,0)
        kernel /vmlinuz-2.4.22-1.2135.nptl ro root=LABEL=/ rhgb
        initrd /initrd-2.4.22-1.2135.nptl.img

change it to

title Fedora Core (2.4.22-1.2135.nptlcustom)
        root (hd0,0)
        kernel /vmlinuz-2.4.22-1.2135.nptlcustom ro root=LABEL=/ rhgb
        initrd /initrd-2.4.22-1.2135.nptlcustom.img

13) reboot
Now if none of us have made any typos you should be able to reboot your system and choose the new entry from the grub menu.

The above is not going to do much except build a kernel that is most likely very similar to the one you are already running, so you can debate what the value is. But you can use it as a starting point to building a kernel that is taylored to your system by changing the .config file further.

I suggest that you read some of the documentation that comes with the kernel source, start with /usr/src/linux-2.4/README. You can also find several documents on building kernels on the web, try google.

Good luck
