To set up genkernel to work with your bootloader, three or four changes should be applied to the bootloader's configuration file:
1. Add root=/dev/ram0 and init=/linuxrc to the kernel parameters passed to the kernel image.
2. Add real_root=/dev/hda7, for example, to the kernel parameters passed to the kernel image, if /dev/hda7 contains your root partition.
3. If you are using bootsplash, add a suitable mode line such as vga=0x317 to the parameters passed to the kernel and also add splash=verbose or splash=silent depending on the verboseness you require from your bootloader.
What is verboseness
4. Add the initrd information as required by the bootloader. Consult the Bootloader Configuration Chapter of the Gentoo Handbook for details on how to make your bootloader initrd-aware.
title=Gentoo Linux 2.6.12-r10
kernel /boot/kernel-genkernel-x86-2.6.12-gentoo-r10 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3 udev
So I need to add real_root=/dev/hda7 udev and what about ramdisk=8192
genkernel users should know that their kernels use the same boot options as is used for the Installation CD. For instance, if you have SCSI devices, you should add doscsi as kernel option.

Just boot up with your Gentoo livecd and chroot into your installation.
Check the handbook for the necessary details on chrooting.
The kernel works now but I can't log into Gentoo it rejects my username and password.
log in as root
useradd -G usb,wheel,video,audio -s /bin/bash username passwd username
it won't log me in as root and won't accept my root password
you probably forgot to set one during your install. Go back through the process you used to chroot. Once in the chroot just enter
[enter new root passwd]
then add new user if you haven't done so
Would I do this in the terminal
