BTW - The hope was to find a tweak/patch for OS X to avoid having to spend $169 on a Matrox DualHead2Go, which will work for using 2 Analog (15pin) monitors (see DualHead2Go compatibility list, Mac system info at bottom of page).
(UPDATE: Matrox now has a "Digital Edition" that supports DVI displays, as well as "TripleHead2Go" models.)
A PPC Mini owner wrote with some notes on using the DualHead2Go:

" I have a Mac Mini (G4 1.42 MHz, 512 MB) working fine with a Matrox DualHead2Go. This might not be precisely what you had in mind, but it does allow 2560 x 1024 @ 60Hz. Fine for Final Cut Pro and Avid DV Xpress. (I assume he's using LCD displays, as most would not want to use a CRT at 60Hz due to flicker)

Interestingly it carries over the bug that Dual screen Avids had with Matrox cards, the overlay is sluggish on screen 2, but fine on screen 1, when running Quicktime viewers. Placing the mouse on the QT screen overlay gets it going again. It is although a screen refresh callback is missing in the drivers or hardware. Below is the System Profiler grab. As you can see, Mirroring is not supported.

If 2560x1024 is selected, one screen 2560x1024 spanned across two monitors each 1280x1024
If 1280x1024 is selected, mirrored 1280x1024 on each screen, so mirroring is supported but not reported in System Profiler

(The Intel-based Mini has onboard Intel GMA-950 graphics, also supported by the DualHead2Go, as is a long list of other graphics models.)
Another Mini owner mentioned using the splitter cable for easy switching between a monitor and projector:

" I have a Pacific Cable splitter, the VGA end goes to a touchscreen, the DVI end to a Panasonic PT-AE700 projector. This setup works, but not simultaneously: i.e. I cannot switch on both displays at the same time. But it saves the hassle of changing the cable from touchscreen to projector.
-Ben H."

Update: In Oct 2008 a Mini owner sent a report on the EVGA UV16 Plus USB-to-DVI adapter.
