Mine are a couple of DEC workstation tubes, that are really Sony GDM-1961 (1960?) models. One of those similar Sony models actually supported seperate H/V sync, but just didn't have the extra BNCs soldered into the back signal input panel, and the other model didn't support them at all. My model is the one that didn't support them. :\ Picture is nice and sharp though, but dang, those things are heavy.
If anyone needs some assistance setting up the drivers, I'll try to help. At least with the millenium, you would have to: 1) hack the MGA.MON text monitor description file to add the timing parameters for the Sony CRT, 2) use Matrox's DOS-mode software to read in that text file and generate a binary config file specifically for your attached CRTs, 3) using W2K's out-of-box MGA drivers, make a registry tweak to get the driver to load the data from the binary-compiled version of the MGA.MON file, which you also should copy to \WINDOWS or \WINDOWS\SYSTEM or something. Note that doing things this way, you will not be able to use Matrox's newer drivers, nor their desktop-management tools, although you can actually run those drivers in parallel with the out-of-box drivers, if you're careful, because none of the binaries' filenames overlap.
The key ability to support sync-on-green, is actually part of the discrete TI 302x RAMDAC included on the board, not the Matrox chip. Matrox doesn't "officially" support this capability, which is really and truely too bad, because Matrox is basically the "king of 2D", and easy support for workstation-class fixed-freq/sync-on-green CRTs would just enhance their market position there, I think. Interestingly, my Creative Labs Permedia2 PCI card also contained that same TI RAMDAC, but I have no idea how to mod the Permedia drivers to get it to work.
