Is there any advantage to using the viafb?

I need to milk as much performance out of this as I can and it seems that
some forum posts say that it should be blacklisted.

It's kind of hard to tell what is the accurate, current information for the
openchrome 0.4.0.

Does anyone have a clue where that symbol is defined?

I've done

scanelf -r -s vgaHWFreeHWRec /lib/* /usr/* /opt/*|grep vgaHWFreeHWRec

and found nothing, but I found this:

scanelf -l -s vgaHWFreeHWRec | grep vgaHWFreeHWRec
ET_DYN vgaHWFreeHWRec /usr/lib/xorg/modules/drivers/cirrus_alpine.so
ET_DYN vgaHWFreeHWRec /usr/lib/xorg/modules/drivers/apm_drv.so

Am I not loading a module that needs loaded?

Is that an X module or a kernel module?

I'm literally not getting anything from google except this:

https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1280292

There apparently is virtualbox on this machine and it says it has an error
starting it.   I don't need nor want it right now.

No, that was worse.   I spent a lot of time fighting it.   The strategy I
ultimately came down to was that I needed to upgrade to 0.4.0.

When I run glxgears the fps went up from 20 to 60 after the upgrade.   I'm
really tired at shooting in the dark with this thing.   Do I need to load
the vgahw module in the X config?   The dri or dri2?

Anyone have a working X config file with this chip set?

TIA,
