Mpact AGP Adapter?

[Bill Schmitt (software)]

I'm new to FreeBSD and am attempting to install it on a Gateway PII/300. 
The graphics adapter isn't being recognized. A little research and I've 
learned that the motherboard has an integrated MPact AGP adapter, and that 
was subsequently acquired by Chromatic Research which was then acquired by 
ATI which dropped all support. X doesn't come up in any intelligible form 
(either a garbled screen or nothing at all). Can anyone point me to where I 
might find information on getting this to work? (there's really no 
information at all about it on the Gateway site except an executable for 
reinstalling it under Windows)

Thanks,

Bill
