Kernel Panic!!! Can't find modules.dep

Question

Hello, everybody,
Yesterday I followed the Kernel Compilation From Source topic on arch's wiki. So i did:
wget -c http://kernel.org/pub/linux/kernel/v2.6 … 31.tar.bz2 (not 2.6.28)
cp linux-2.6.31.tar.bz2 ~/kernelbuild/
cd ~/kernelbuild
tar -xvjf linux-2.6.31.tar.bz2
cd ~/kernelbuild/linux-2.6.31
make mrproper
make menuconfig
I didn't change nothing in menuconfig.
So I created PKGBUILD and kernel26.install
makepkg -c
pacman -U kernel26-my-2.6.31.5-1-i686.pkg.tar.gz
Everything with no problems. Except for one thing. When I did "pacman -U kernel26-my-2.6.31.5-1-i686.pkg.tar.gz" it returned conflicts with: vmlinuz26.img and *.map (I don't remember the names, the first it something like vmlinuz26.img but the second I only remember the extension *.map, I problably can remember if i see the names again). So I deleted these 2 files (I thought the new kernel would create these 2 files again).  After delete them, I runned again "pacman -U kernel26-my-2.6.31.5-1-i686.pkg.tar.gz", now with no erros. I restarted and BOOM!!!
When I start appears the ERROR: could not load /lib/modules/2.6.31/modules.dep: file not found
But I started from my Ubuntu and I can see modules.dep there. Maybe, it is searching in the /boot directory, instead the /
What I must to do now? Is there a way to recover the old kernel? I think I made a backup. But I don't know how to access it, because my Ubuntu can't (only the owner can) and I don't how to use the live cd, because I know the Ubuntu-like live cd, but I can't find a live cd for Arch. So, is there a way to solve the problem? Please, reinstall Arch is the last option.
----------- EDIT ---------------
Maybe I have to configure my bootloader (GRUB). But how do I do that?

Actually, turns out I was reading that when you posted.
Here's where I'm stuck.
After mounting proc, sys, and dev I did the mkinitcpio but now I receive:
ERROR: '/lib/modules/3.0-ARCH/' is not a valid kernel module directory
Which is accurate, because my /lib/modules is 3.3.4-1-ARCH. 
So I checked for what could be setting that incorrectly with
grep -r "3.0-ARCH"
Only thing I found was in etc/mkinitcpio.d/exmple.preset
But even in that file the line is commented out with #fallback_kver="3.0-ARCH".
I didn't think I was using any defaults since I specify the -c command to mkinitcpio.
Where is it getting this 3.0-ARCH kernel version from?
