unable install due irql not less or equal error

When I try to install Vista Beta 2 I gen a blue screen with the error 'irql_not_less_or_equal'. Initialy the install goes through the load files froccess (white bar indicating progress). After this completes the splash screen showing longhorn appears for about 5 secs then it blue screens and dumps the memory with the above message. I am attemting to install it on a Dell Latitude D610 with a 20gig HD and 1 gig memory. Anybody had this problem or have any idea how to get round this?
PS I managed to install Beta 1 ok so looks like its a new 'feature'

Do the install again, be there when it blue screens and do not allow it to boot back to Vista/setup after the blue screen, but instead:
1. boot back to previous os, 2. change folder options to make hidden folders visible before the search. 3. search all partitions (may not be visible! * -> diskmgmt.msc -> assign drive letter) for .log files. The interesting log files are 4 to 30 MB in size, sometimes at vista partitions windows\inf directory if the setup went that far. Submit these logs to microsoft using Beta Client.
*If there was no vista partition in diskmgmt.msc* then the log files are most likely in the same drive your previous OS was installed (if it had space for the setup files). There should be a hidden, weird named folder, in root of the volume and the logs are somewhere under there (search).
