[Savage40] T22 DRI black screen

[nand]

I have an IBM T22 laptop running Debian Sarge. I have installed the Debian XFree86 => Xorg upgrade which includes DRI from http://www.nixnuts.net/files/binary/ and it doesn't seem to work quite right. The "savage" DRM module supposedly works with my card (the PCI ids match up) and the Xorg savage driver loads and reports this error:

(II) SAVAGE(0): 8844 kB of Videoram needed for 3D; 8192 kB of Videoram available
(EE) SAVAGE(0): Insufficient Videoram available for 3D -- Try a lower color depth or smaller desktop.  For integrated savages try increasing the videoram in the BIOS.
(EE) SAVAGE(0): DRI isn't enabled

So I tried a lower resolution.

Now, whenever I start X with a resolution and/or color depth low enough to leave enough videoram for DRI, I just get a blank screen and I have to actually power off and back on again before I can see anything again. Rebooting does not help, the screen remains blank even through the BIOS and GRUB. Looking at /var/log/Xorg.0.log over SSH, DRI claims to have loaded successfully. Does anybody know what the problem is?

Thank you,
