[BUGS] Xorg 7.3 with Intel 82915G

[Jerahmy Pocott]

Yes, me again >_>

I'm having problems getting X (xorg 7.3) working properly with this  
integrated Intel 82915G chipset (at least that's what dmesg says it is):

agp0: <Intel 82915G (915G GMCH) SVGA controller> port 0xecd8-0xecdf  
mem 0xdff00000-0xdff7ffff,0xc0
000000-0xcfffffff,0xdfec0000-0xdfefffff irq 16 at device 2.0 on pci0
agp0: detected 7932k stolen memory
agp0: aperture size is 256M
pci0: <display> at device 2.1 (no driver attached)

(Not quite sure about that last line, is that a problem?)

Any way, I can get X running if I use 'vga' driver, but that driver  
only supports 8bit and the fonts are unreadable. The device settings  
that Xorg -configure generate are thus:

Identifier  "Card0"
Driver      "intel"
VendorName  "Intel Corporation"
BoardName   "82915G/GV/910GL Integrated Graphics Controller"
BusID       "PCI:0:2:0"

How ever trying to start X results in the following:

(WW) intel: No matching Device section for instance (BusID PCI:0:2:1)  
found
(II) Module "ddc" already built-in
(II) Module "i2c" already built-in
(II) Module "ramdac" already built-in

(EE) intel(0): Couldn't allocate video memory

Fatal server error:
AddScreen/ScreenInit failed for driver 0

I tried adding the line 'VideoRAM    7932' to the Card0 configuration,  
but this had no effect. I also tried using the i810 driver but it had  
the exact same error. I think that some of these integrated cards  
"share" some of the system memory? How do you get these cards to work,  
any ideas?

Thanks heaps,
Jerahmy.
