I seem to be having a similar/same problem on my Toshiba Tecra A10
laptop, with an external display attached.

$ lspci | grep Display
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

Laptop resolution = 1280x800
External display = HP LP2465 at 1920x1200

I have the latest intel driver (2:2.6.3-0ubuntu5).

On Ubuntu 8.10 this setup runs fine (except the external display becomes
the primary).

On Ubuntu 9.04 I can only get the external display up to 1152x720
When I try to set it to 1920x1200, this is what happens on startup (from Xorg.0.log): 

(EE) intel(0): Failed to pin front buffer: Cannot allocate memory

Fatal server error:
Couldn't bind memory for BO front buffer


I tried the Option "Legacy3D" "False" fix, but that did not do the trick.
 
I'll attach the Xorg.0.log. 

Oh, here is my xorg.conf (identical in 8.10 and 9.04): 
# xorg.conf (X.Org X Window System server configuration file)

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
	SubSection "Display"
		Virtual	3200 1200
	EndSubSection
EndSection

Section "Device"
	Identifier	"Configured Video Device"
EndSection


Should you need more information, don't hesitate to yell. 
Kind regards

Geert
