I have found that the problem seems to be with the sdhci driver.
I have posted a message at http://ubuntuforums.org/showthread.php?t=287939&page=4 under the name skrpc detailing what I did to get a version of linux on an X56 laptop. I had to use Debian 4 (Etch) as this was the only installation I could find that did not freeze and allowed me to complete an installation. It froze when rebooting after the installation had completed but as the installation had completed I could use rescue mode enabling me to rebuild my own custom version of the the linux kernel (2.6.18.4) and by a process of driver elimination led me to remove the module load of the sdhci driver and all works ok now albeit using Debian 4 rather than Ubuntu.
