nForce3

[george+freebsd at m5p.com]

Good news and bad news on my Compaq R3120US.  FreeBSD doesn't seem
entierly happy with the Nvidia nForce3 chip; specifically the agp
driver.  (It complains twice in the printout shown below; the second
is from when the ltmdm port is trying to attach to the Agere modem.)

The good news is that USB seems to work fine.  My USB floppy attached
without difficulty, although the umass driver generates some scary
messages in the course of normal operation.  The USB mouse worked the
moment it was found.  I have a Prolific USB-Serial adapter, which
seemed to be recognized by ugen, but it doesn't seem to have
created any serial ports.

My main question is, does anyone have patches for agp which would fix
whatever problem is indicated by the "Unable to find NVIDIA Memeory
Controller 1" message and let me attach to the Agere winmodem?
