xorg resolution on new laptop


Hi folks,

I've scoured Google seeking wisdom, and found nothing except hordes of
Linux users whining about this same problem. FreeBSD users don't seem
to have this issue, except for me. Finally I have no choice but to
throw myself on your tender mercies.

I've been going nuts trying to get 1440x900 resolution on my new
Toshiba P105. Any help anyone could offer would be greatly
appreciated. Xorg assures me that the 945GM video card is supported
by the i810 driver, provided I use the 915resolution program to set
the resolution before starting X. I run:

/usr/local/bin/915resolution 3c 1440 900

to add the resolution 1440x900 to the video BIOS. 915resolution -l
now shows me:

...
Mode 3c : 1440x900, 8 bits/pixel
...
Mode 4d : 1440x900, 16 bits/pixel
...
Mode 5c : 1440x900, 32 bits/pixel
..

So, in theory 1440x900 should be available to the card.

startx fails without a config file, so I let it create one and tweaked
in based on gossip, rumour, and innuendo I've uncovered in three days
of Web searching. I get something that looks *about* like 1200x768,
but it's a far cry from 1440x900.

pciconf -lv tells me:

...
vgapci0@pci0:2:0: class=0x030000 card=0xff311179 chip=0x27a28086 rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'Mobile Integrated Graphics Controller'
class = display
subclass = VGA
vgapci1@pci0:2:1: class=0x038000 card=0xff311179 chip=0x27a68086 rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'Mobile Integrated Graphics Controller'
class = display
...

Here's relevant stuff trimmed from my xorg.conf.

Any ideas, anyone?
