You don't have to know, all the ET6000 cards are similar, because
RAMDAC is integrated to the chip.

It seems that it's basically using the bare VGA only.

These confirm that.

This is most probably the cause. I assume that you're using 1.3.0 or newer
version of SVGALib as you mentioned et6000.regs file. Those et4000.regs and
tseng3.exe are meant only for ET4000 cards, which come in different flavors
and thus can't be treated as one kind of card. But as said, ET6000 cards
are basically all the same. That's why you don't have to change the
et6000.regs file which comes with SVGALib 1.3.0 and newer. Just copy it to
/etc/vga/et6000.regs and you should be ready to go. Check your
/etc/vga/libvga.config that you have enabled the ET6000-driver first
(although it should autodetect the driver if you haven't forced any). After
that you should get all the usual screen modes, but the driver doesn't
support too much accelerations so testaccel might still fail (can't test
anymore, just changed my ET6000 to TNT last week)
Anyway, good luck :)
