Here is a little bit more detail.
Both the i830 and i855 share the same memory configuration. I own both a Dell D400 (i855) and a C400 (i830) SNAP never supported the i830 but before buying a used D400 I had checked for i855 support. It was a real letdown to end up with the same problem on both machines. Reading the SNAP forum, If the bios didn't support setting the shared ram value, You are out of luck. Reading intel's support forums, They blame the manufacturer's for being too cheap to add the bios options.
I think the affected # of laptops is much larger than I thought. It seems to be commonly used in many laptops that have 12.1in and smaller screens. The memory architecture for the intel i9xx series is slightly different but close enough that only a few mods may be required to fix the whole family of video processors.
Thanks again for asking the developers to look at it and I can provide dumps or any other details/testing if needed.
