SQL Server 2008, MAPS and VMWare

I came accross this post from Buck Woody recently, and I thought it would be an excellent opportunity to try out SQL Server 2008 on a VM and serve multiple purposes at the same time. Well, even though my VM has 4GB of RAM allocated, the MAPS install fails with insufficient Physical RAM (95 MB). I’m not really sure how to get around this but if anyone has any ideas I’d love to hear them.
