Steps to reproduce: download the driver from intel's home page. Built it by
adding the drm_agp_t structure (removed since 2.6.10 from kernel tree) fix the
pci_restore_state and pci_save_state too. try to load the module after the
compilation:

You'll have to update the Intel driver to use remap_pfn_range instead.  It's 
the same as remap_page_range except that it takes a page frame number instead 
of a page.  Typical change is something like this:

Problems with external drivers don't belong here.
