Hey all Blaggers,
I forgot to register in my rush to post (so I am he who was Jojo and guest). Just a little update, the kernel parameter I used to get my Blag install up and running was 'bf24 nomce noapic pci=off', this sorted out my keyboard not working, and got me into the installer. The guide at http://devel.reinikainen.net/docs/how-to/n1015v/
deals with Debian installs, but it should help you out if you have a similar strange Compaq laptop as me.
Thanks, and looking forward to being a full time (laptop user) of Blag.
