xserver-xorg-video-trident broken for cyberblade/XP

[Beeblebrox]

I have an old laptop with a Trident Cyberblade/XP video card. tridentfb has
been broken for this model card for some time now.

# service lightdm stop
# modprobe tridentfb (from tty0)
Screen goes black then shows stripes with light and dark areas.

* I'm only able to get a gui environent by forcing vesa in xorg.conf and not
loading tridentfb.
* With vesa, screensaver locks-up the system (no tty, no caps-lock response)
so that's been disabled.
* Debian jessie-i386-lxde (new install)

Try to reinstall a stable to see if you encounter the same problem
('cos this looks more VRAM problems than driver to me).

This problem exists since 4 previous generations of Ubuntu. I just
recently switched it to Debian and get the same problem (not
surprisingly). Switching to some other version on Debian is not going
to help.
Might the problem be acpi related?

May be, try some kernel switches about it.

I'll see (not now, missing time:( how it goes on my very old
laptop that also have a Trident GC (but it worked OK one year ago).

I placed on the linux line of grub.cfg
acpi=force lapic=debug
to no avail. Do you have any specific suggestions?

Also try acpi=off (! may broke the boot)

Here's a bootparams list:
https://www.kernel.org/doc/Documentation/kernel-parameters.txt
(you'll see that there are debug options for acpi, might be interesting)

Also try something about apic.
