Aha. That made the second output magically appear. Thanks!

I was having problems in compiling things in kernel. Eventually, it
seems they were limited to compiling the latest 2.4.20-pre10-ac2
patch, which contains a more recent version of your material. With
that, both with modules and included in the kernel, I get the
following messages (here with modules);

PCI: Found IRQ 9 for device 00:0b.0

matroxfb_crtc2: secondary head failed to register
matroxfb_crtc2: CRTC2 framebuffer failed to register

so that I cannot see the second head of the g400. With 2.4.19 and
module loading, instead of the last two lines I get:

matroxfb_crtc2: secondary head of fb1 was registered as fb2

This is not urgent for me now. I still cannot see if the output is
present on all outputs (somebody will have to physically check the
monitor outputs, and that will hopefully happen sometimes tomorrow),
but now the matroxset output looks very promising. 

In all cases, if you want me to do some tests or try some patch to see
if the 'failed to register' situation can be fixed, just ask.
