If you don?t need that much video RAM, I?d reduce this value.
>From the looks of the Display sections below, you don?t need
that much. You could get by with 8192 or 16384.

This is a module versioning problem. The i830 module needs to
be recompiled for your kernel.

This will go away as soon as the module loads and creates
the device.

Device file for the video card.
