CentOS 5 Hardware :: Compiling Custom Kernel For Apple Intel XServe

I need to compile a custom kernel for my xserve1,1. Or are there people who already managend using centos on their intel xserve? The current centos 5.3 kernel configuration does not support EFI. Right now I am able to boot the installation of centos to the welcome screen
and get stuck at the part where I need to skip or run the cd test. (keyboard and mouse won't work)

Just the boot screen
Screen where I pick option 2, the cd installer
Image shows ubuntu but it is centos. forgot to change the menuentry description name in grub.conf
ROMimage present
The screen that I see after image 3
The screen that I see after image 3
The window of centos

I tried the centos 5.3 86_64 DVD and netinstall. I already managed to run debian/ubuntu on my xserve1,1 with use of refit + grub2 but I need centos to use cpanel...
