State of i810 driver?

I have just bought myself some new hardware - a Core 2 duo on an Intel DG965SS
motherboard (which is of course 965G based).
Running the machine in X86 mode, I upgraded the linux kernel to 2.6.19-rc2
following a note on here which said it was necessary to get an up to date
agpgart module, and I now seem to have a basically working system.
I am running Debian Unstable - which means the version of the driver as of now
(in Debian terms its 2:1.7.2-1 - but I think it maps through) is 1.7.2
Running a normal kde desktop it seems to work fine - but as soon as I attempt
to play a video I get the display driver appearing to crash in some form of
loop (about 10 seconds long). The only way out seems to be a hard reset of
the machine.
I did try to capture the log (before it got overwritten on the reboot). The
latest time I did it, there was nothing in it after the normal startup. The
previous time - the following was at the end - but that was before I took out
a VideoRam 17000 line from xorg.conf (which I had accidentally left in there
when I was trying to figure out the problems that required me to upgrade to
2.6.19-rc2)

Is this a known problem? Is the fact that it appears to want 128M as opposed
to 64M something I can do something about with an option in Xorg.conf?
I have also seen talk of the "modesetting" branch but I am unclear if I need
to be thinking about that (since again I think I have read somewhere that you
need it to change the memory setting from a BIOS derived value).
I saw a thread which suggested that it might be being made available to Debian
Unstable shortly. If its needed in order for playing video, then I am all
for it.
