I ran into the same issue when upgrading from wheezy to jessie today on an age
old IBM R30.
I could solve it without recompiling by upgrading
xserver-xorg-video-trident
from 1:1.3.6-2+b2
to 1:1.3.7-1+b2
which is available in testing(aka stretch) now (as of 2016-04-17)
compare
https://packages.debian.org/de/jessie/xserver-xorg-video-trident
and
https://packages.debian.org/de/stretch/xserver-xorg-video-trident
I used apt-pinning to keep dependencies consistent.
It updates quite some other xorg stuff (54 files, see below)
I didn't care for details, because it was the last hope before a fresh
reinstall. Looks like it works like a charm :-)
Maybe it would be nice to provide this approach in a proper backport to jessie
(supposedly aka "stable")?

some Details:
On boot (the first boot after dist-upgrade), you see a short flash of console
login, and then the screen gets dark.
Machine responds on ssh login, but keyboard is dead.
I could narrow down the issue by disabling kdm on boot.
Starting kdm manually reproduced the problem
I found this line in the /var/log/Xorg.0.log :
(EE) TRIDENT: Failed to load module "xaa" (module does not
exist, 0)
Googling it dropped me to this Bug page.
The driver manual
ftp://www.x.org/pub/X11R6.8.0/doc/trident.4.html
lists the chip - "CyberBlade series i1" -
still as "supported"
