There is no lspci in NetBSD. The approximate command is pcictl, and
with "pcictl pci2 list" I get this:
002:00:0: ATI Technologies product 0x95c5 (VGA display)
002:00:1: ATI Technologies product 0xaa28 (multimedia subclass 0x03)
which ist the ATI (Asus) EAH3450 video and audio.

The base system doesn't have to know the video card, except for the VGA
compatible part to do console text. The Xorg radeonhd driver supports
the card, at least well enough for me to work with.

Well, I don't know where to tweak a setting. Here's an excerpt of
Xorg.0.log when it fails to initialise the radeonhd:

My VGA monitor is connected to Connector[0] in above output, i.e. to
"VGA CRT2". The monitor isn't recognized through E-EDID. When running
in native mode, it is detected and used:

It looks like the I²C device isn't working under xen33 and so the
monitor can't be detected.
