[Intel-gfx] 82845G/GL[Brookdale-G]/GE support for more resolution and external display

I have an old laptop with on board 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03) which only has 640x480 available using the xf86-video-intel v2.99.911 driver with xorg-server 1.15.1.  Additionally, I cannot use an external monitor attached to the onboard VGA out which I know is good since I can use it under another OS.  Is this old chipset still supported?

I attached Xorg.0.log.  Thank you for any advice I can use to get the full set of resolutions since running in 640x480 is not workable.
