Yeah, there wre lots of them so I just did mkinitrd --builton=ohci ... and all modules that it said it couldn't find as reading on the tutorialas it said that it was safe tyo ignore usb errors as they are built into the kernel, but my mkinitrd just stopped so I had to tweak it until it didn't complain no more.

In the meantime I'm just building a new kernel so you have any sufggestions appart from this to install the kernel:

cd linux-2.6-xen
make clean
cp -a .config .config-old
wget -O .config <http_url_to_config_file>
make oldconfig
make menuconfig (if you need to change something)
make bzImage
make modules
make modules_install

# in the following lines replace "version" with the actual kernel version you're compiling.
cp -a .config /boot/config-version
cp -a System.map /boot/System.map-version
cp -a arch/x86/boot/bzImage /boot/vmlinuz-version

# And then generate initrd/initramfs image for your dom0 kernel, example for Fedora/RHEL/CentOS:
mkinitrd -f /boot/initrd-version.img version

Were there any errors when you did a make install? Such as these:

WARNING: No module ehci-hcd found for kernel, continuing anyway
WARNING: No module ohci-hcd found for kernel, continuing anyway
WARNING: No module uhci-hcd found for kernel, continuing anyway
WARNING: No module ata_piix found for kernel, continuing anyway
