i810 woes

I'm trying to get MythTV working on a fairly crappy i810 chipset 
integrated PC.  When Myth tries to use XvMC, the display shows a blue 
rectangle, and the sound comes out OK.

The blue windows is the same color as the blue X shows when an overlay 
window fails.  This is confirmed when Myth shows the following error:

2007-03-19 20:54:42.352 VideoOutputXv: XvMCTex: Init failed
2007-03-19 20:54:42.353 VideoOutputXv: XVideo Adaptor Name: 'I810 Video 
Overlay'
2007-03-19 20:54:42.364 VideoOutputXv Error: CreateXvShmImages(): 
XvShmCreateImage() failed to create image of the requested size.
2007-03-19 20:54:42.364 VideoOutputXv Error: CreateXvShmImages(): 
XvShmCreateImage() failed to create image.

The only thing vaguely resembling an error in the Xorg.log file is:

(II) I810(0): [drm] removed 1 reserved context for kernel
(II) I810(0): [drm] unmapping 8192 bytes of SAREA 0xd0b8d000 at 0xb7a9d000
(WW) I810(0): xf86UnMapVidMem: cannot find region for [0xb3a1d000,0x3000000]

The chipset is ID'd as

(--) PCI:*(0:1:0) Intel Corporation 82810E DC-133 CGC [Chipset Graphics 
Controller] rev 3, Mem @ 0xe8000000/26, 0xeff80000/19

DRI is enabled.

My device section:

Section "Device"
        Identifier      "Intel Corporation 82810E DC-133 CGC [Chipset 
Graphics Controller]"
        Driver          "i810"
        BusID           "PCI:0:1:0"
        Option          "XvMCSurfaces" "7"
        Option          "LinearAlloc"   "16384"
EndSection

Head of the Xorg.log file:

X Window System Version 7.1.1
Release Date: 12 May 2006
X Protocol Version 11, Revision 0, Release 7.1.1
Build Operating System: UNKNOWN
Current Operating System: Linux hermes 2.6.18-4-686 #1 SMP Wed Feb 21

The system is Debian Etch, freshly installed.

I would appreciate any help or suggestions; I'd like to know why I can't 
get an image....
