I've checked in patches for AGPGART and DRM. You'll need to apply them
manually if you're having problems (a.k.a. crashes :-) when starting
X. To do this:
 cd linux-2.6.8.1-xen0 ; patch -p1 <../linux-2.6.8.1-patches/*.patch

I'm really interested to know (a) if with the patch X works; (b) if
not, why not [e.g., crash dump]; (c) if the patch works with Xen, does
it also work with native Linux (i.e., have I broken the normal case!).

Gerald: my patch has a better chance of working than yours as I also
fixed the page-allocation call to definitely return a
physically-contiguous extent of memory. If it doesn't then I gues
we'll have to see whether anyone with a serial line can help.
