Might be old news to you, but today a couple of new entries were added to the XFree NV-driver by a NVidia employee Mark Vojkovich, who has been maintaining the driver for some time. The new entries are, named by the PCI device ID:
0x0180
0x0181
0x0182
0x0188
0x018A
0x018B
0x01F0
0x0280
0x0281
0x0288
0x0289
It seems these have already appeared also in 30.82 drivers for Windows, but from the nv-driver source one can see some features the chips will have and with which chips they are closely related.
1F0 seems to be the NForce 2 as it is programmed in the same way as NForce before it. All the new chips have similar clock crystals as GF4 MX and GF4 Ti now have and support dual head. 18X and 1FX are setup with the same code as GeForce 1/2/4MX, 28X with GeForce 3/4 Ti code. There seems to be a clear division of Quadro models that begin with XX8 and the normal models that begin from XX0 in both 18X and 28X
